We also fought with Crutchfield for at least 4 years about them saying 5" speakers fit our cars and the 6.5 didn't. Their credibility is questionable.
A good choice I think. There's a long history of this and the PAC SWI-X working in our cars. The X is designed with an IR interface to the aftermarket radio making it somewhat universal but if you can select from a handful of brands (including JVC and Kenwood) you can use the JACK version for a direct interface.Last week I worked with Metra to confirm that the Axxess AWSC is not compatible with the serial control channel used in our cars and yesterday ordered a PAC SWI-JACK ($36 shipped!) after reading the above testimonials.
