Does anyone know if Sony is coming out with a Navi unit? I know alot of you ppl dont like sony products, but I have a Sony LCD screen and i want to get navi....will other navi units work with my screen? are they compatible? ie. alpine, pioneer....

 

i think sony came out with something back in the 90s (self-contained garmin-type system i think) so i doubt if they will try again. i think most navi systems use rca outputs so it's probably ok to mix and match.
