Since my new truck gets crappy radio reception and I'm not to crazy about paying the XM radio fees, I've been lookin into getting a ipod, I been researching this that past few days but havent come up with any solid answers, I've thought about trying to find a 2010 radio with the USB port, havent found one, then I looked in adapters, I've heard the name periphal thrown around, USA spec pa20, and i found out GM has there own interface called PAL, does anyone here have any experience with these?
