    Bluetooth -> Serial -> HD Radio

    I have been looking on ebay at bluetooth RS232 items. Most do not seem to support the DTR line that Mitch's cable uses to turn the radio on/off.

    Is that okay? I mean if you power the radio's trigger line from another source anyway, is it necessary?

    Is the DTR line just for software control of on/off?
