dsteinmann Posted December 18, 2008 Report Share Posted December 18, 2008 I Have a D3 that wont read the real 07 nav disc or a burned 08 its not in a car but on a bench and just the parking brake is grounded do i need to do the other bypass for it to update the maps or does it need a gps antenna? Also is just pushing the reset button all thats needed to reset the unit or do i have to hold it down for a while to get a full reset or something? Quote Link to post Share on other sites
