nav radio in ss

[04silveradoSS]

I just purchased the 04 silverado SS ...equipped with the six disk indash xm bose system. First i must say for 42,000 one would think that this truck would be equipped with nav stock....but no. So now I am faced with the task it looks like u guys have been succesfull with.

ok the question is when u re3moved ur stock deck did the unit just plug and play with the existing harnress ....or did u have to cut and hardwire?

one more question is since mine is currently the six disk indash system and will be removed .....what changer can i hook up to this unit?

thanks for any help!!
