Vaguely to do with computers but might be worth asking. I have a TomTom 710. Using the Home dock connected to the PC it is not now recognised despite working for the last three years plus. Power is being received at the Dock and the TomTom is being charged and works OK in the car. Whilst it was connected to the PC (and not functioning) I waggled(?) the connecting cable at the dock end and it sprung in to life. I moved the dock subsequently and it says yet again "USB device not recognised". This suggests that the dock is faulty. I cannot quite figure out as to how to gain access to the interior of the dock to look for loose wires. Anyone out there who might be knowledgeable on this aspect? I know - not strictly a PC question but....... I have posted this query to TomTom and also a TomTom forum, but responses are not overly rapid.
My 520 connects as you describe and not normally by direct USB. However I've just checked and the connection to the dock is a USB port and I have now connected by the USB cable that I normally use for syncing my mobile and I have successfully bypassed the dock.
Woodchip Are you saying that your cable used to sync your mobile phone is the same as the connection on your 520. If so, what mobile phone is that? I have ones for LG, Nokia and Sony Ericcson and none of thos appear to be the same sort of connection as to the TomTom
it does not connect to phone only by i think wireless or infrared blue tooth don't know about that one as i do not connect phone. I do have traffic alert connected to the bottom of it. This picks up from side of road
