I got a 2004 Chevy Trailblazer EXT, hookin up my D3 to it! Got everything together and will play CD's and radio. But I'm not sure where to splice into for the speed wire and the reverse wire. Could somebody help me with this? Get at me!!!!!

Almost forgot! Do you know if the factory Trailblazer Double din stereos that come with XM have the tuner built in the the stereo or is it external? Do you have XM on yours, if so what was yours like? Holla

Cool, I was gonna get that too! So it won't affect the Pioneer it seems! Thanks Pimpin!

What it dew? Getting ready to buy my Pioneer D3 navi. Saw on this thread the way to bypass the lockout. I have a 2004 Trailblazer EXT I want to install it in! Accourding to crutchfield they say I should use a Metra GMOS-01 GM OnStar Class II Interface in order to keep my factory door chimes and keep my onstar working! Could anyone verify that this will still work correctly! I think I may still need the harnessing kit for the trailblazer also, what do yall think! Holla back [/img]
