I don't know a whole lot about writing code or anything, but I do know that the old stand-alone Pioneers(AVIC9/90/80) were NavTeq. Now you can buy the new TeleAtlas software and stick it in those models and it works fine, so I don't think there is a conflict between using teleatles or navteq as long as Pioneer is doing it. ...
Wow, very interesting. Well maybe I am wrong. Having a standard for "map" data / databases would be very cool. You then could do a cross referencing system for locations and routes and other neat things. Hmm....
Actually whtcrxghst you seem quite knowledgeable about these systems. I was wondering how much know about the AVICs internals. Specifically the IO for it's add on systems (DVD changer, Sat Radio, etc.). If your or others knowledge is as extensive as I hope I can start a new thread for my questions.
