I just retired the '82's factory tape deck and replaced it with a RetroSound Model 1.
I'm impressed! Having installed several Pioneer, Alpine, JVC, and Kenwood head units to name a few, I can say I wasn't familiar with RetroSound. But the thought of cutting the original dash was out of the question- so an alternative was what I was looking for.
What interested me in the Model 1 was the USB and SD capability. I didn't mind losing the ability to play cassettes or CDs so as long as I had the ability to easily play MP3s. I don't own an iPOD, so an MP3 player via AUX connection wasn't something that interested me. And really, those systems rely on the MP3 player to do all the heavy lifting- and then treat the car stereo as merely a set of external speakers. But not the Model one- it has USB, SD, and two AUX ports. It also has an RDS decoder so that it shares radio station and song detail. If I upgrade to a system with an external amplifier, it has front and rear RCAs. And, it has a remote.
The install was easy and there was a lot of ability to tweak how it fits in the factory dash. The owner's manual was easy to read and understand.
I have almost 600 songs stored on a PNY 16gb thumb drive- and still have almost 12gb of space left.
So, overall I'm very pleased with it!
