hmmm here's a Q as far as audio...
 

Ok..my 05 H2 doesnt have the NAV system...just the stock radio w/6 disc changer.
My Q is can i "upgrade" to the nav system without any snags? ie rear audio still function/ steering wheel controls still usefull ect.
If this is the case then possible somone out here has "****canned" there nav system for pioneer ect and wouldn't mind parting with their old system :popcorn: what say you?
