And it was simple. The IPOD goes in the center console or wherever you want to put it. For those installing one, the dip switches are 3 and 8 on. The instructions scare you into thinking that you will have to strip power wires but you do not have to. You can use part of this link http://www.vetteessentials.com/instr...zel_howto.html to take out the radio. You don't need any of the cables that come with ISGM73 but you need a PXHGM4. It was easier run the PXHGM4 to the area behind the ashtray and plug it in to the ISGM73 so the radio fits back in. Just to add everything I learned doing this there is no radio security code. If anything I said above is wrong can someone correct me? Thanks.
