Car Audio / Tint Suggestions

I live on the south side of Indy and am looking for the best tint shop in the area. I could use the same place that did my Infiniti M35x (Buster's in Greenwood) but want to make sure I use someone that has worked with Corvette's before. I also want to do 20% all around, except the front, which I know some shops won't do because off legal issues.

I would also appreciate some suggestions for car audio shops to add a subwoofer, amp, touchscreen/nav unit and backup camera to my Corvette. Any suggestions on specific touchscreen/nav units? Thanks!

I would use Ovation in Castleton for the audio.They do a lot of high end systems. Not sure about tinting.
