My 9616T-LM has suddenly decided that it no longer wants to provide the correct time. i'm not talking about a zone problem, but a completely wrong clock. I'm off by multiple hours and minutes. I did try the "tools" and a complete reboot as well as manually entering the location for the unit but no luck. I don't use the GPS that often and only noticed the problem a week or so ago after having had the unit completely out of service for several months. Mapping works fine as well as the address book showing all stored information. The unit isn't that old and has very little use. I will not replace it should there be no fix. i have another unit and my phone can handle the job if necessary, but I would prefer the Magellan be working correctly.
