I finally completed the solution. I purchased a Pioneer 5700 radio/cd/dvd/sat radio/with ipod connection and had it installed. It also has an input for a backup camera, which I did not need as I already have a backup camera.
I have a 9 inch tablet that I have loaded Delorme SW on and will use this for my GPS.
Cost me $550 for the work, life is good.
