Hi, I'm new to this forum. I would like to update the map on my Kenwood kna-g510 unit but can't find any instructions or for that matter which map I would need to use. I plan to update the firmware on the unit as instructed on the garmin site (KNA Series, Ver. 4.20, as of Mar 09, 2012).
As for the map, the garmin site latest download for my unit is City Navigator® North America ...
