I installed this myself, 2008 Nissan Frontier, in about 3 hours with the GPS system. Overall it was very easy to install and I had no major issues. The deck will use the factory brackets that are attached to the factory radio, which was nice. You will not need to use the adapter kit, just the wiring harness and antenna adapters. The GPS system has been used several times now and have had no problems, it finds it way everytime. The HD radio is awesome and comes in crystal clear. I have used every option this thing comes with but the bluetooth and have had no issues ever. The only nit pick I would have would be that the screen is a little hard to see with direct sunlight, but I believe you would have this with any screen. Overall I am very pleased with this unit and would recommend it to anyone.
