My first 08 Wrangler Unlimited had the normal radio (no upgrade). The sound from my ipod when turned up was not too good. Some popping especially on low frequency sounds like a base drum. When I turned the ipod down this problem seemed to be diminished. This sound problem appeared on the satellite radio too. I did see a post somewhere that indicated that there was some kind of firmware upgrade that the dealership could do that would minimize the problem. There is evidently some kind of mismatch between the satellite radio and the amp. This seems to agree with what I was hearing out of the speakers. I'm a master electronics technician registered with the state in radio and television so my ears are pretty in tuned to things like this. On my new 08 Sahara Unlimited Rubicon, I got the upgraded system with upgraded speakers. The radio also plays DVD movies. My ipod plays much better on the aux port. Still no info on the display but the sound is pretty normal. The best part of the upgraded radio is that it comes with a Hard Drive for ripping songs from CDs or MP3 recorded CDs. I've done very little experimenting with this yet but am looking forward to it when time permits. Hope you find your solution. You will hopefully post back here when you find something. And BTW, welcome to the forum.
