how much are you getting the 01 stock deck for?

Considering you can fit 10, 192KBPS albums onto one MP3 disc, 6 disc changers are pretty over rated now. Also consider your audio source. If you burn your music from MP3's to audio discs, why even bother with the changer?

Anyways, back to the topic ...

Your new radio should plug right in. If you have a trunk mounted changer, you will lose that. On the V2 G6 decks, the attachment input was removed.
