Hey guys, first, I am glad you guys are liking the settings for your car's. That's very good to hear.
Second.. The IPOD sounding brighter.. The internal EQ of the IPOD must be set OFF. I mentioned that in the original post, but I understand it was a bunch of reading so it could have been missed. But turn the IPOD EQ off. It should not sound any brighter, louder or different than an MP3 CD. Original store bought CD's will always sound better than a burned CD, MP3 or IPOD.
The settings were done with all types of media, not just the IPOD.
