Either way, I want navigation. The choice is do I get an RB1, or an aftermarket piece. I know how to by-pass all the infinity stuff if I do an aftermarket unit, but I would really like to have the convenience of a factory unit so I can use my steering wheel controls. If I go RB1 though, I'll lose more detailed control of all the sound, no EQ, dedicated sub pre-outs, etc... If I go aftermarket, it'll have to be a fold-out, and I'll more than likely need a separate changer, as the main slot will probably have to have the nav dvd. I don't want a multiple cd system, and I don't wanna have to do my destinations ahead of time and then load them to the unit. Basically, it's a matter of if I wanna sacrifice sound, or convenience. I just wanna amp my main speakers, and add 2 12" subs in the trunk, similar to my old set-up in my old Intrepid. Although I think i'll be going with more power this time, with better subs. I was thinking of maybe tracking down some Adire Shivas, or maybe some Kappa Perfects. Nothing crazy, but enough to rattle the earth if so desired. Any thoughts, comments welcome. TIA...
