Here's what I want to accomplish..( long story to follow )

What do I need to buy?

Vehicle is an 06 X5 3.0 with Nav.

#1) Satellite radio - now this may be a nit, BUT I already have an XM contract that goes through 2009. Today I am running my XM via an Audiovox XC9 which I have stowed in the center console, plugged into the 12V lighter in the back for power, via FM Modulation, with a magnetic antenna on the roof. I am NOT a channel surfer, in fact during the week it's on 127 (CNBC) almost all day, and on weekends 46 (TopTracks). With the anticipated, dare I say, pending XM/Sirius merger it seems foolish to buy a new XM radio now. BUT it does look pretty trashy with wires hanging over the seats and out the door and console.

#2) CD Changer - I planned on installing one, primarily because I listen to books on CD during extra long drives, and have a large CD Collection. But got to thinking how I rushed to install one in my wife's E46, and I dont think we've EVER used it.

#3) MP3 Player - Although I don't have one, bought my wife and my 16 y.o. have an Ipod. Maybe I'll move into the new millenium one day and buy one, but in any event, I think I need to be prepared to have this option available, even if it's as simple as an AUX port in the glovebox.

#4) Back-up camera - Vehicle has PDC, but with little ones running around my street, I'm overly paranoid about being able to see behind me. There is a guy out of Germany selling BMW OEM retrofit ones for about $499 on ebay, with lots of goood feedback, that I have considered.

#5) TV on the Nav Screen - This is last on the list as a nice to have, and seems like some places offer NAV/Backup Camera combos.

Let me add one other point. I am PARANOID about breaking stuff, so unless it's real easy (ie, I installed the CD changer in my wife's convertible in about 30 minutes), I need to be sure there are places I can go to that will do the work for me..or friendly X5World buddies close by to help .

So what would you buy..?

Thanks
