He also tried as first unit on the bus as there's only a BOSE amp. Oddly enough, whatever was downstream from the GW500 failed (the bus wouldn't recognize it.)
BH Porsche was kind enough to verify MOST bus for me (verified that the Head Unit had CDC enabled as well...) The end game was this unit DIDN'T work on my bus. It kept killing the BOSE or the head unit.
Any thoughts????
Also, the Porsche documentation / fiber packet that comes with the kit says the GW/CD bypass switch doesn't work on Porsches... yours does??

Hmmm - I didn't get the notice about the bypass switch not working, but that explains why I couldn't get the configuration menu to come up (it requires 3 cycles of the bypass switch).
Does your car have NAV?
With the Gateway 500 installed, do the rest of the devices work? I.e. Can you hear the radio and/or CD? This would indicate that your installer didn't reverse the input vs. output, and that your Gateway 500 is getting power.
What I'm trying to get at is that I've read that the CDR23/24 requires recoding using the dealer's PIWIS system when adding a CD changer. The PCM can, however, auto-discover the addition of a CD changer. I'm no expert, I just read this somewhere about installing a CD changer.
Since the Gateway 500 emulates a CD changer, a CDR23/24 head unit would need to be re-coded using the PIWIS system by your dealer.
I've also attached the install notes for Porsche that were provided to me by maxcount.de - I just received this yesterday. Note that there are two different DIP switch settings for Porsche, depending on whether you have a PCM or CDR23/24 head unit. It also mentions whether the Gateway 500 should be up or down stream from the head unit.
