For the sat nav as has been mentioned use the plug by the battery, and if you go to a BMW dealer and ask for a cable part no 83300413585, you can then splice this to your Garmin power lead and just plug in, its around a tenner. The 3 leads are marked, 1, 2 and 3. Lead 2 is not used, 1 is earth and 3 live.
I believe Nippy Normans may sell plug and play cables, but they are about 40 quid.
Cant help with the Intercom, I dont want to hear or speak to anybody when Im riding but thats just me.
