    USB Radio

    After a bunch of reading, Ive learned that there are basically three solutions for carputer radio:

    - cheap USB modules by Silabs or a Radioshark or whatever
    - the HQCT module from MP3Car
    - a Visteon Zoom thing with a cable from MitchJS

    Is this right? I want to use the Zoom so that I can get HD radio and analog radio. Also, is there a schematic for the serial cable MitchJS sells? I saw people mentioning it but couldn't find it.

    Thanks.

    U should get the Visteon with Mitch's cable so you can enjoy the new HD technology.

    Can I make Mitch's cable on my own instead of paying 25 bucks? I have quite an extensive electronics background.

    I'm sure you can make the cable, however u need to have someone that has it look at it and try and get the pinout.

    Well I can like reverse engineer mitch's board, but is there a simple schematic available instead?

    Maybe, but I can't remember if it is this cable, or one of his others (like for the Sirius radios, etc) that it is more than a pin-out. I think there's a small chip in one end.

    from the photos i've seen i think there is just a level shifter circuit involved.

    but then again mitch deserves some compensation for his work on the RE and software so i'll probably buy one from him when i get a module.

    See, Im going to be writing my own software anyway so all I want is the cable. It looked like just some level shifting -- which would explain why there could be a chip on some. Mitch's looked like just a transistor and a few resistors, some others might use the MAX232 or whatever it was to shift serial levels.

    Can anyone maybe find this pinout for me? Im having a lot of trouble finding it in Google... what the hell shoudl I search for! haha
