It's sure on my list of possible improvements. I just hate having to mess with stock dash looks.

Strange thing is that Metra isn't a fly-by-night outfit. They make a lot of different things and have been around for quite a while. Unfortunately, it just seems like Bose systems don't like to play nicely with anything else which isn't too surprising I guess. I would like to keep it as factory as possible other than updating the head unit so I'm going to do my best to make this path work. Especially since I've already spent $320 getting all the amps in the speaker pods repaired. And to be honest, the factory speakers do sound quite good.
