I had my Vaistech system installed by Myer Emco stereo and they did a great job. These guys take apart all kinds of cars, Mercedes, Jaguars, BMWs, Audis, they know more about taking the interior of a Lexus apart and putting it back together than the Lexus dealer I bet...
Just find a good shop that does high end cars. They charged me $75 to install my Vaistech kit, and I can't imagine it would be more to do the Lexus kit since its plug and play.
These guys fabricate entire custom sound systems, rework door panels with fiberglass, having them do something like this is like asking a brain surgeon to put some stitches on a cut...they can handle it.
Wrong. They cannot punish the dealership for failing to follow their pricing guideline, it is an ANTITRUST violation, it is illegal.
Lexus does hold dealers accountable for customer satisfaction surveys, but they cannot punish them for charging less...or more...than the MSRP for a product or service.
I don't see people complaining when they buy cars for less than MSRP...its the same thing...just in reverse.
