I am no car audio buff, but I have had success with panasonic, pioneer, and JVC head units. Luckily for me, whoever had my se-r before me installed very high end Kenwood tape and CD components, so I lucked out. The improvement is amazing, but probably is no reflection on their low end stuff though. I had a panasonic head unit in my last car, not unlike this one:
