It was very hard to find a place to trust for my Porsche Cayanne GTS. I had searched and called several places, but Xtreme Car & Truck Accessories had the most reassuring reviews and they were good to work with. I brought my baby in to change the whole interface system and keep the Bose speakers and back up camera intact. I was pleased to see my car after the work was done. I've had several cars with stereo upgrades done and sometimes there is mess/debris in the car or chipped wood grain on the panels, but the craftsmanship was great. They are reasonably priced and the system has been working great! read full review »
