What company makes the best jack for mp3/ipod for the XC90? I understand the FM modulation plug in does not work well at all. Any help would be appreciated.

 

Waaaaaaaa Forget the best, just get the one with the longest cord. Trust me the extra foot or two will come in handy.

 

In the same vein, where is the radio antenna located on the XC90? In my Acura, it was in the rear window glass near the defroster traces. When I installed an XM radio with FM modulator, the kit came with a long wire to get the signal all the way back to the antenna.

Is there a "best practice" for FM modulation in an XC?

 

I believe that its also a glass element type antenna.
