I wish to hook up my ipod to the factory 20 disc in dash stereo. I have tried those crap fm transmitters that never work right. So I found this Newegg.com - AUDIOVOX FMM100A FM Modulator with Isolation Transformer
fm modulator. Was going to order it but by reading the reviews I found out that some cars have different antenna plug sizes so it may not fit my volvo. Does anyone know??????

 

You are right, the factory plug is different. You would need an adapter between either end of the FM modulator. They can be found on ebay pretty easily.

Something like this
Between the antenna and FM modulator:
VOLVO RADIO Wire Antenna Adapter Cable 1998-2009 | eBay

Between the FM modulator and head unit:
VOLVO 99-up Factory Radio to Antenna Adapter | eBay

I hope that helps.

 

IMIV, IMIV, IMIV, or if not available, USAspec...Ijust installed an IMIV in our 02 V70XC and it is FREAKIN AWSOME!

 

Ok THANKS!! debating now if I should go that way or just buy a alpine I have been eyein.
