Hello everyone,
I saw a few other threads with something similar going on (but they're kind of old now) and the proposed solutions didn't work for me.
I have a TomTom XL 340 Live IQ Routes Edition GPS. On the bottom sticker, it shows up as a Canada 310 / XL Live. On the TomTom Software, it's a 340 S.
Anyway, problem I have is that the device no longer connects to my computer. It comes up as 'unknown device'. I've tried 3 cables, 3 computers, using Windows 7 x64 Ultimate, Windows XP, and Windows XP x64. I've tried it without installing any software at all (since it's supposed to show up as a flash drive) and that doesn't work at all. All of my thumbdrives work just fine, so it's not a computer driver problem.
This happened after I tried using TomTom Home software to try to write a route to the GPS. After I did, it errored out as it said 'no maps installed'. After which, I couldn't gracefully disconnect the GPS from the TomTom Home software. Leaving the GPS connected, I powercycled it and when it comes back on, it now shows up as an 'unknown device' for every computer it's plugged in to.
I get this screen:
But not this one anymore:
It sits there and spits out the 'unknown device' error on every computer and cable combination I have.
This also comes with the RDS traffic receiver and that no longer works either.
I've tried the 15 second software reset which didn't work... tried the reset factory defaults which didn't work. Tried combinations of both which don't work.
The device works perfectly otherwise - I can still map myself anywhere without issue. However, map updates no longer work, I cannot add any content at all, and because this device doesn't have a flash card to utilize, I have no other way to access the device period.
Is there a way to make this thing format itself completely to re-enable the ability to access the internal flash memory?
I had also done a couple of updates before trying to write the route from the software which took just fine.
After performing the factory reset, I noticed 2 custom icons I had loaded were still there... I thought doing that was supposed to eliminate ANY custom content including icons and the like.
The device still recognizes that a computer is attached. It'll ask me if I want to connect, I say Yes, and then it reboots and then it would normally come up to the screens above but then it stops and I don't get the second screen, and then it spits out the unknown device. If I disconnect the USB cable in this state - it WILL load and then go back into the regular GPS mode.
I've tried the soft reset while it was off and then powering it on... tried the soft reset while it was on and then letting it cycle on and off... tried the reset while connected to the computer, tried the reset disconnected, tried the reset connected to the RDS traffic receiver, tried connecting it to a USB hub and without it... I cannot get this thing to show up as anything but 'unknown device'. The error message Windows spits up is:
USB Device not recognized - One of the USB devices attacahed to this computer has malfunctioned, and windows does not recongize it. For assistance in solving this problem, click this message. Tried all the general windows troubleshooting, but it does this on all of my computers (and I have almost a half dozen).
I don't have a problem cracking this thing open. I've done it before as I had dropped the unit and cracked the digitizer, so I needed a replacement screen, which I did myself. I tried running the unit out of battery power to see if that would make it reset too and that was a no-go. I could always try disconnecting the battery, but I'm sure this is a software problem.
I'm at a loss. I tried other 'tricks' such as tapping the screen as it powers on to see if there's a different diagnostics screen built in (I've already seen the DOS based one where it gives you serial numbers and the like). It bugs me that there is no external way to access this thing at this point. Any suggestions or recommendations will be most likely, as my warranty is almost up. I got it around Christmas last year and this thing has kind of been a curse.
