Tomtom Go 730 device not recognized Solved

Question

Hello,
I bought a TomTom Go 730 GPS two months ago and everything was working perfectly until now. When I connected the GPS to the computer, it would ask me if I wanted to connect to the computer, and I would select "yes," allowing me to do everything I wanted with the TomTom Home software. However, overnight, when I turn on the GPS to connect it to the computer, a little bubble appears at the bottom right of my PC screen: "USB device not recognized, one of the USB devices connected to this computer has malfunctioned and Windows does not recognize it." When I switch ports or even computers, the same thing happens; the driver installs correctly, it indicates that the device is ready to use, but 10 seconds later the same message appears...
Can someone please help me? Configuration: Windows XP Firefox 3.0.4

Hey hey I think I found it! Finally, it worked for me and I should have done this a long time ago: press the RESET button with a pen under the TomTom. No more problems! It was just a simple GPS bug like what can happen with any electronic device!
Maybe you should try that too!

Hello,

I am experiencing exactly the same issue and have been since almost the same date.

I have not yet been able to resolve this problem.

I am in the same position as you, waiting for a response.

As for the support phone number, I haven't been able to reach anyone.

I hope we can resolve this issue quickly.

Best regards.

Since the same period, I am in the same situation..  I think it's the last update that caused this. If you ever have a solution, I'm interested!

cash · Answer

Indeed, I also successfully performed a reset yesterday (and on top of that, I didn't lose anything, neither configuration nor favorites...).

mrmarc · Answer

Hello everyone, same problem...since the update...on the same date...
except that it happens every time....the reset is a last resort....there should be another solution..

it's a tomtom issue that needs to be resolved other than through a reset.....

See you, marc

Hello
I’ve had a live 940 for 2 days

On my PC running Vista, I have the same problem as you with TomTom Home 2.5
USB device not recognized.

I then tried to install it on another PC running XP and with version 2.3.1.92 (CD provided with the TomTom live 940)
same issue: device not recognized

I tried your reset manipulations but without success
I emailed TomTom and I'm waiting for their reply.

If you have any leads, I'm interested.
There seems to be a real issue since I have the same problem on 2 PCs with different configurations.

Best regards

Hello

Tomtom suggested several manipulations but without success.
They are telling me to return the machine.

There must be an identified problem because they didn't hesitate long before telling me to return the machine...
I'm still surprised, but oh well...

zdail · Answer

Yes, a little reset underneath the device and it is once again recognized by the PC running XP.

tryton · Answer

I have a GO730 and I had the same problem as you... But the reboot fixed the issue... Strange nonetheless!!!

Djill · Answer

Hello,
My GO730 just displayed five lines while it was no longer recognized by my computer, although I had never had any problems until today. TomTom's online help is completely unbearable; fortunately, a search on Google directed me to this forum where I immediately found the solution. It indeed only took a reset of the device to set everything right.
Thanks to those who posted the solution on the forum.

tomtom go 730 same problem as you, but the reset doesn't do anything... changing the USB cable doesn't help either... tried on 3 PCs... I'm desperate!

Eric2 · Answer

Tomtom go 720

Same problem as you; USB device not recognized. Tried the RESET but nothing works... and I've even tried on 3 other PCs and a Macbook... still impossible to recognize my tomtom via USB...
This happened since I wanted to reuse my tomtom after 2 months of inactivity and tried to update GpsQuickFix... before it worked perfectly for over a year so I don’t understand...

eglander · Answer

Look here  Have a great evening

Eric2 · Answer

Thank you, but it's no better than what I've already done,
- battery charged...
- tried several resets and maneuvers to connect the Tomtom hot to the USB or not...
- tried on several PCs and a MacBook...
- tried with a standard USB cable, small USB connector for the Tomtom and large USB connector for the PC...

in short, I think there's a problem with my Tomtom Go 720... or the Tomtom USB dock is no longer working.

I have to try at a friend's place who also has the same USB dock and a Go 720... if it doesn't work at his place either, it's definitely my device's fault,,, and that's a bummer... what else can I do, it's not even under warranty anymore!
Idea: can we change the internal battery of the Tomtom Go 720...? a new battery connected internally to the USB port could change the behavior of the Tomtom. at the same time as getting a new battery since mine only lasts 50 minutes today...

eglander · Answer

Indeed!!! Troubleshooting procedure here

or contact TomTom service there

When the TomTom is connected with USB, the green light should be on indicating that the TomTom is charging.

For battery maintenance here

and battery replacement here

good luck

Eric2 · Answer

Thank you for these links, especially for the battery; they will be really useful to me.

Just for your information, the green light on my Tomtom turns on when I plug it in via USB, it recognizes it even because it asks me the usual question of whether I want to connect my device to the computer...
... when it's the first time on a new PC, it does say "New hardware detected"... then "Your hardware is ready to use"... but systematically it ends with "Unknown USB device"... and my device is completely invisible to the computer.

eglander · Answer

If it worked before, I think you should talk to TomTom via the email or other contact on the site I gave you.

If you tried it on several PCs, it’s not the USB port but the TomTom.

Have you checked by going to Start, right-clicking on Computer, Properties, Hardware and Device Manager, and then clicking on USB port?

You connect your TomTom to USB and start it. Normally, you should see a window pop up and you click on read files.

However, you need to properly disconnect your TomTom, meaning without turning it off by directly pressing the power button but via USB.

Have a good day.

eglander · Answer

"Have you checked by starting, right-clicking on My Computer, Properties, Hardware and Device Manager, and clicking on USB port?"

Sorry, you also need to add and check that there are no yellow exclamation marks or red question marks, and check it again after starting the GPS.

Eric2 · Answer

Yes, thank you, I had already checked in the Device Manager; there is no yellow exclamation point or red question mark once the TomTom is connected to the PC via USB. I even uninstalled all the USB controllers (except the one for my mouse) in that manager and restarted the PC to force Windows XP to reinstall them, then reconnected my TomTom, but nothing worked... yet everything seems to go well at first: "New hardware detected"... then "Your hardware is ready to use"... then after a few seconds: "Unknown USB device".

I don't think this is related, but just in case... about three months ago, I noticed that my TomTom cigarette lighter charger was no longer working (no more little green light and of course no more battery charging in the car)... I also tested it with my children's PSP cigarette lighter charger (same output voltage) and the same USB plug as the TomTom; since that worked well, I continued to use my TomTom for two weeks. Then I put it away in the cupboard as I didn't need it for two months...
When I took it out again, I wanted to connect it to the PC but couldn't turn it on (it must have been completely discharged), so I left it to charge on the PC dock and then used it again with the PSP charger in the car as before, and it started up and worked like it did before....
except for the fact that I can no longer connect it to the PC via the USB dock with the symptoms mentioned above...
That's also why I was thinking of trying with a new battery and buying a TomTom brand cigarette lighter charger.

eglander · Answer

In my opinion, the battery is good since it works; if I were you, I would contact Tomtom for advice, there is a USB problem with the Tomtom since it does not work on another PC  Have a nice day

Eric2 · Answer

I tried with a friend who also owns the Tomtom Go 720 and I couldn't connect my Tomtom either. The problem clearly lies with my device.  I can't reach Tomtom's phone support; it's just an endless musical answering service... So, I will try through the internet and email, but I expect standard responses and copy-paste replies from the support team...

eglander · Answer

Our phone lines are particularly busy on Mondays and Tuesdays, and we apologize for any inconvenience this may cause. Therefore, we recommend that you contact us later in the week if possible, or submit your question through the online help on our website.  Personally, at this address, I came across a very knowledgeable person with precise answers here  Hoping everything gets sorted out. Have a great day!

ARZU · Answer

Thank you very much, it works by doing "RESET". Great!

Eric2 · Answer

Unfortunately for me, nothing works; the Tomtom Go 720 does not want to be recognized via USB.  After contacting Tomtom support on their website, and after some unsuccessful advice, they eventually suggest that I open a repair ticket and send them the device. I'm not too thrilled about this because we are on the eve of the school holidays, and that’s when I’m really going to need it... so I think I will wait until September before deciding to send it to them. Furthermore, they don’t want to give me a price estimate, and whether any kind of warranty could apply or not (?) What do you think? I bought it in November 2007, less than two years ago...

eglander · Answer

Look here or there and again here  These are 3 consecutive chapters  And never forget to back up your Tomtom before any manipulations on PC as explained here  Hoping everything will work out one way or another, have a good evening.

eglander · Answer

Have you tried on another PC?  See you!

eglander · Answer

Indeed, it's getting complicated. Have you tried without TomTom Home to see if the GPS is recognized as a device? You have USB 2, I believe USB 1 is not fast enough.  See you soon and talk to you tomorrow.

pepebougon · Answer

Thank you for the wise advice! I should have started with that!

M@th · Answer

Hello everyone,  I received some news from Tomtim support, they offered to contact me themselves.  Which was done yesterday morning, we tested the GPS together to see what wasn't working.  As nothing was happening, they suggested I send it in for repair. But since that seemed strange to me, I tested it with the dock and not just with the USB cable alone. And the miraaaaccccleeeee it worked.  It seems then that this problem comes from the USB cable alone and not from the GPS.  Anyway, I’m relieved that the GPS is working properly.  :-)

Indeed, it is necessary to reset. Thank you for the information.

piloux · Answer

Thank you for the tips. After a reinstallation of Vista, my TomTom Go was no longer recognized. The reset fixed everything, I pressed the power button for several seconds (20 seconds), reconnected it, and voilà, a thousand thanks to you all.

fdr · Answer

Thank you for the rest of toomtom go 720, I hadn't thought of that, and it works.

aiasi_42 · Answer

By the way, uh, nothing to do with my original problem but I have a really annoying issue: this *@$*!% GPS won't connect right away. For example, in the morning at 6:30 AM I need to travel 80 kilometers to get somewhere, and my GO 730T doesn't connect, "wow"! (not to be vulgar) I'm thinking! Well, I start to leave because I more or less know the first 30 kilometers, and then after 6 kilometers it picks up 1 or maybe 2 small bars, well it's still better than nothing except it places me at least 30 meters off the road, meaning in another street, so it recalculates the route every time, and then it loses the signal for a minute, then it reconnects but only with 2 bars and so on... and that until I arrive (by the way I don’t even know how I made it!). Or it doesn’t connect at all, I have to wait, standing still, for a good 10 minutes for it to catch the signal! And I've tried a lot of resets, nothing works. -- Windows 7 Ultimate Edition / Linux Mandriva

bastiou15 · Answer

Well spotted with the Reset, my PCs no longer recognized my GO730... It seems like it has to happen at least once to each of us... PS: For those who are not in the loop, check it out here: http://www.wikango.com it helps avoid paying the subscription even though I admit it's not top-notch because the GPS often announces radars that are for the other lane in the opposite direction, better than nothing at all.

Hi everyone, where is this "reset" button on a TomTom Go 750 Live? Did they remove it or do I have sausage skin in front of my eyes?????? lol

Press and hold the power button until your device restarts. This may take about fifteen seconds.  Have a nice day
