does any one know of the best way to keep onstar and use an aftermarket hu

 

any one like to anwser...

 

Ran across the solution at a local stereo shop. It is an interface unit that allows the normal use of Onstar with ANY head unit. It is quite pricey, though. The price I got was $120. I will go back and get more information on it. Stay tuned to this thread and I will let everyone know who makes it, model number, etc. It has LOTS of connections, looks a bit complicated.
