My 2002 is a 1.5 din. Just found a replacement stereo myself. Pyle marine grade (water resistant) and UV resistant to fading....CD with anti-shock (minimize skipping in a bumpy Jeep) and port for adding the IPOD/MP3/DVD player. I just wanted something simple, clean, and to do its job without a lot of extra crap I couldn't figure out.
It was extremely hard to find a 1.5 din to fit the stock hole. If you are interested, PM me and I will send you the specs and website.
