Navigation Retrofit

[FeelGoodUnInc]

i've decided to go with the navigation retrofit...i just bought a 16:9 widescreen monitor...i spoke to Colin of SavageBMW and he told me this:

"I’ve been looking around for you Aaron. There is no ACTUAL retro kit from BMW. However, my good friend Chris that used to work @ Crevier helped out one of the X5world members to do his. I checked on some of the parts and some are no longer being produced. I’m not sure how bad you would like to have it, but I’m sure it would be very taxing on your patience and expensive to boot! If you would like me to, I can check availability on the entire parts list and get back to you. From what I hear from Chris and read on the forums, a lot of outside resources are required to complete the installation. If I had to take a preliminary guess, I would have to say that it would cost between 3 and 4 thousand to totally retro. Eeek! Let me know what your thoughts are and we can go from there."

since parts are no longer being produced where else will i be able to look around for them besides ebay?

also i was told if i don't have DSP i need a BMW amp...i have a JL audio amp so im curious if i can use that. i didn't know the retrofit would have so many obstacles...thanks in advance!
