Bumping this up...I'm with someone else who said I'm going to love this vehicle as soon as I get the darn infotainment crap fixed. I need nav for sure. Any other input on aftermarket units? Are the presets like the lights etc. really the ONLY thing that is lost going this direction? I like the steering wheel controls and am afraid this will be lost. Also what's the impact on the backup camera? I plan to have whatever I choose professionally installed so I at least get some kind of warranty on the work.
