I just want to say that I installed this ************* last weekend and I think it sucks. Yeah it plays just fine but the nav screen is just about useless for finding what you want on your ipod with 10 gigs of music, movies, and pics (or more). This thing is very, very, very low tech. I regret greatly the $200 I spent at Best Buy on what cost some Chinese sweat shop probably about $3 to make.
To answer your questions Yargnits:
1. Audio level is fine, its the same as the radio as far as I can tell.
2. You can't have more than one device playing at the same time. You switch to the ipod and whatver was playing before stops playing.
3. yes, it will charge so long as you hook this thing up to RAP like it tells you. If you decide to hook it up to switched accessory power (not what the instructions tell you to do) it will only charge while the vehicle is on.
4. I have no idea.
My opinion: Unless all you want is a way to get your ipod sounds to your speakers, don't waste your money. It won't let you do anything else. No song title display, no album name/number, no artist, no idv3/4 tag info no album artwork, no playlists, noooooothiiiiiing. POS.

I hate to tell you this, but you apparently didn't hook up the PXAMG.
1: There is no wiring to do, so you can't NOT hook it up to RAP.
2: It does do text display, playlists, etc. Does them very well, actually.
You can even choose elapsed time, artist or song title as the default display.
You have PEBKAC issues.
