Very Happy!

We really like this radio, had some difficulty figuring out the wiring but the folks at Sonic were absolutely great at sorting it out. The customer service was top notch.

This product solved my problem

I have a 1998 F150 Extended cab Silver Anniversary Special that I bought new. I finally decided to upgrade the audio system with a Pioneer Bluetooth Radio. I ordered or purchased three separate wiring adapters that were suppose to work for this conversion but the did not. This truck had a separate power amp that was not in the original radio. I called Sonic and their technician told me I needed the Metra 70-5603. I ordered it and the installation was easy and the new receiver works as advertised.

Easy!

This made the installation of my Dual XDVD176BT so easy and the best thing is SE gives it to you free with the purchase of the receiver. Thanks, Sonic Electronic.
