2002 BMW X5 FM modulator?

yes, easy as cake, but the modulator will cost him $20, as well as two antenna adaptors for the European radio plug. each $20. so it will cost you $60 just in parts alone. the Audiovox Switching Box will work with the XR9 and will turn on and off when the power to the XR9 is turned on and off.

hope this helps, but even the modulator with needed antenna adapters is not cheap, but still cheaper than a Blitzsafe DSP aux input adapter.

let us know if this helps. i installed a Dension Ice>Link plus in a 2001 X5 about six months ago. the radio is easy as hell to get to and there is more than enough room to put the modulator behind the radio/cd player. 

well, if you're looking for cheap, seems the cheapest is on Crutchfield, unless someone knows of another website, as it would be $60shipped, free shipping. you know Crutchfield redesigned their website? just laid out diffeent now, hard to zip right to where you need to go now. but looks a lot slicker, lot more color and pictures, more gloss.

how and where did you mount the XR9? i put the Ice>Link on a Panavise vehicle specific mount, as the driver wanted open, easy access to the mounted Ipod.
