Motorola Blue tooh car Kit

[lous320]

I am Installing A Motorola Blue tooth car kit. I would like to know the location and wire color of the Audio Mute wire for the PCM. and if I could run audio thru car speakers. :help:

My first 4/10/04 post in this topic has the wiring information. My 5/2/04 posts list, show and identify the sources for the required parts.

The vehicle will require the dealership to use the PST2 to toggle the phone status to enabled so that the audio will come out the right front speaker. Otherwise the mute will work, but no sound will come out.

Don't know if you are installing the IHF100 BLNC (Motorola) but if you are.....I've just had it installed and would offer the following.

connect the constant, ground and mute, from the radio wires. FYI you'll have to make a lead for the mute as the radio mute wire isn't present...I believe it is pin 3 (your installer will find it no probs)....DON'T take the ignition sense from the radio area, take it from a spare switched fuse (found in the fuse box, by your left foot).....

I found this out the hard way....Basically the ignition is pretty unique on the 997, in that you can for a limited time operate the pcm without the key in the ignition, or after you switch off the car. Because of this, when you deactivate the alarm, it switches on the bluetooth for a few seconds, and more importantly if you are on a call, then switch off the car, the bluetooth remains in handsfree mode (doesn't transfer back to the cell phone). This keeps the radio switched on for as long as the call lasts....There is a possibilty this throws a 'system fault' to the Porsche onboard computer as it isn't able to switch off the pcm.

Finally, when you program the handsfree kit, I suggest you have the engine switched on, again because of the above.
