Hi terminator1, Just a thought with your GPS issues - from your previous post it sounds as though you have the Caska style unit with two SD ports at the bottom of the unit. Did the supplier of your unit provide you with a demo or trial GPS software? If they did, and if this software at least loads, then you may need to follow the same file structure. If there is a startup file (startup.txt, system.ini or something similar) then you will need to copy this to the root folder of your SD card and with a text editor change the startup file to direct it to the correct program file. Hopefully that makes sense :) Good luck and look forward to seeing the photos of your install! ...including the headrest monitors!! NEW UPDATE: ITS ALIVE ! I finally got the gps working with a Route66 file. everything is in working order. you can have the radio still on whislt your gps is working, radio cuts of when gps talks and same with phone. The after market dvd head rest are of top quality and can work as one or seperate systems with wireless head phones. ALL IS GOOD ! Will send pics of all by week end sorry guys but all this mucking around with unit has made me behind in work. CHEERS ALL
