Radio Upgrade - Sunstar 27PE
The first upgrade I undertook after purchasing my Sunstar 27PE was to replace the factory radio and speakers. The less said about the Jensen speakers the better, while the radio was small, difficult to see, didn't have a volume knob, and didn't support Apple CarPlay. They all had to go.
Replacing the speakers with Kicker 5 1/4" round ones was an easy swap. The radio was a little more involved. I chose a Jensen CAR910X with a 9.1" adjustable screen. The problem was the Jensen was single DIN and the factory (Pioneer) double DIN. This necessitated 3D printing some brackets and a cover plate.
The result was everything I had hoped for and more. I know get great sound, CarPlay, and a screen I can see.
