It's just occurred to me that the mute connector is probably being used by the Blue&Me unit. So I guess I will need to disconnect that? However I have read that this can cause problems with the odometer flashing. Is there an easy way around this?I've just purchased a Dension Gateway bluetooth lite for my 159 with Blaupunkt 939 head unit. Seems to be working well, however I couldn't work out where to plug in the telephone mute lead. Is this needed? If so where does it go?
Actually I've realised that I can connect to both Blue&Me and the Dension Bluetooth at the same time, so when a call comes in the Blue&Me handsfree takes over which is perfect as I'd prefer to keep Blue&Me for calls anyway.If you have a look at the thread below you will see the 159 connection diagram. There are no leads specifically for telephone mute etc. it is all controlled through CAN1 and CAN2.
Disconnecting B&M will cause flashing ODO. MultiECUScan should be able to turn that off but I couldn't get MultiECUScan to connect to the body computer on my car so left B&M connected.
B&M does not control telephone mute etc. it is only BlueTooth and voice control. Steering controls are direct to head unit.
