New X5 4.4 Mod Assistance needed.

[mdrobc13]

Okay got a question for you guys/gals. Just traded my 2003 X5 3.0 SAV for another 2003 X5 4.4 SAV. Sorry if some of you think I am a nut but I couldn't live with the 225 hp and low torque of the 3.0 (I came from driving a 2002 M3 as my everyday driver to the X5--needed the space for the family). Anyway after research I found that the only options available for my poor 3.0 were either to add about $3500 worth of Dinan parts to get an 10hp gain at most OR add a ESS supercharger at $6000k just parts. So the $5K additional cost of the trade/upgrade was reasonable since I was going to pay it anyway to add not only HP but aftermarket NAV to my 3.0 X5 anyway if I kept it.

By the way I did consider the new 2007 X5 but they want WAAAY too much for the 4.8is in my area ($72k upwards..I can get a Cayenne S with almost 400hp for that equally as loaded) and the 2007 3.0is scared me off with just a 25hp gain over the old model. (didn't want to be where I just was in that power-loss department).

Anyway I need help with these planned MODs/upgrades.

1. Anyway my new vehicle lacks the Xenon factory lighting that I am used to. Anyway to upgrade or retrofit? I've seen some kits on ebay and soem folks selling OEM or Euro sets. What's the general consensus on these?
2. I had OEM ipod adapter but now with factory Nav I have a freakin cassette player behind the nav and factory cd changer. Why does BMW still add cassette players in 2003/4/5 I'll never know but does anyone know of a good way to add ipod intergration WITHOUT losing the changer?
3. Need to add bluetooth integration. What is the best way?
4. What choices are there for DVD player/screens (headrest option) out there besides BMW's option at $2k almost from factory parts?
5. I need to add Angel Eyes but am told or know already that the 2003 X5 it is hard to do because of the way the lights are sealed. What options are there out there now at this time?
