The original Delco ETR Radio in my 86' El Camino, fondly called the Cowboy Cadillac, with Cassette and Clock became un-serviceable in 1995. I replaced it with a Alpine single DIN unit but was never happy with the appearance in the dash. Recently I discovered the #RetroSound Newport 1.5 DIN radio. Had it installed by Nick Tarrant at Sound Werks in Phoenix. The Newport fits and looks great. Now I have the convenience of Bluetooth for hands-free calling and audio streaming. It is compatible with iPod and iPhone, and it plays MP3 and WMA files via USB ports. Very happy with the upgrade.
