I have a Zumo 550 with XM and an Autocom Pro 7 sport. If I connect it as Autocom suggests I feed it directly into the aux input on the Autocom, which will work fine except that I lose the speed sensitive volume. It seems to me that I may be able to feed the audio out into the Aux connection on the radio and the audio in (mic) to the autocom, thereby preserving the speed sensitive volume.
Anyone know if that's possible? I do not have a BMW comm system, only the audio system, but I assume there is an aux input on the audio system since "Aux" can be selected. Obviously if it is possible I would lose the ability to get sound from the Zumo and the radio simultaneously, but I'm not too concerned with that, since I prefer XM ot terrestrial radio anyway.
Alternatively, does anyone know of a means to do it all: preserve speed sensitive volume, get prioritized audio from the Zumo on top of the radio, and have the XM function?
