OK, I found the 6.1 navi hack, this is what you do with the car started or in accessory mode, LIGHT MUST BE OFF... AFTER THE AGREE SCREEN.. hold down the info button, while turning the headlights on and off for 3 times. wa-la... NOW..to get us to enter items while driving...does anyone see a way from here...
You can go much deeper in the menus but there is nothing there as of yet. This has been discussed many times. If you do a search you will find lots of info and screen shots. The only options us 2006-2007 owners have is to cut some wires or buy a device from Coastal.
