Hi I have been through all that, and no it doesnt appear on the desktop for Mac.
Just refuses to be recognised. All other USB devices function as expected, so its not a fault of the laptop.
I am on the latest updates of lion, I have reset the device by holding the pin in for more than 20 seconds. There isnt any more advice on there thats helpful. So completly lost on this one ...
Thanks for the replies though, any other suggestions ?
I am not familiar with the Mac, so all I can suggest is a brute force approach.
On the chance that your cable has been damaged, get another cable and see if you can connect your GPS to your Mac with that cable.
If you have any friends or family with a TomTom, attempt to connect that
unit to your computer. If you succeed, the probable cause is with your GPS, but if you fail, then look for something unusual with your Mac.
If you have any friends or family with a Windows-based computer, attempt to connect your GPS to that computer. If that succeeds, then you may have an issue with the operating system of your Mac. I remember hearing on some of the Photography forums that such compatibility issues occurred a couple of years ago when Apple came out with an OS upgrade, so it can happen.
Finally, sit down and see if you can write out a list of everything
that has changed on either your Mac or your GPS since the last time you know
that you were successful in connecting the TomTom to your Mac. Typical things to think about include:
(1) Have you updated the software on your TomTom?
(2) Have you updated the map on your TomTom?
(3) Have you changed the cable?
(4) Have you dropped the TomTom or yanked on its cable?
(5) Have you updated the operating system on your Mac?
(6) Have you updated any
software on your Mac, especially firewall or anti-virus software?
(7) Have you added any hardware to your Mac?
The above is not a sophisticated approach to solving your problem, but such tactics can often isolate the cause of computer issues.
With best wishes,
