Ok, after weeks of disapponitments and anger I'm finally done with the install. I got just what I was looking for, more "bass" and I did it myself. I think thats what makes this install worth it. Note to all, if you are installing that LAN-01 for onstar, its a pain in the ass. That box is so big, I had to trim off part of the radio bay to get it in there. So thanks to all for your input and if any else have questions about my adventure I will be happy to answer "If I have the answer" Also be care of the antenna adapter you get when installing a new radio. Make sure its the right one. In other words take your radio out, pull the antenna out to make sure of the adapter you need. I had to go out to bestbuy and get the adapter for a chysler to use the AVH-P4300.
