    Phone wiring

    Early 2013 R1200GS (still) Camhead-- my first "modern" Beemer after years of airheads. I'd like to wire a source of power for my iPhone mount so I can use the navigation and music I like. But, what problems will Canbus create for me? I guess I can't just run a fused circuit directly from the battery, or....?
    Your advice appreciated.

    You CAN run a fused circuit from the battery. The bike won't know or care.

    You can tap into the accessory outlet wiring as well. That way you have a timed off circuit.

    Wiring directly to the battery will give you power on all the time and if the mount is charging the phone it will eventually discharge the battery unless the phone is removed or the mount is disconnected.

    Thanks. That gives me an opening. My mount has a switch and I typically take my phone with me when I'm not on the bike.

    As far as I am aware, most BMW's have a connector for NAV power located somewhere near the dash or forks. Many without the NAV option have the plug wire tied to the area near the dash/forks. You can buy the mating connector plug that you can wire into whatever mount or device you are using (or you can cut the wire and wire in direct). There are 3 wires, positive, negative and a speedo pulse wire that doesn't need to be used. This is a switched power supply that has a delayed off once the bike is shut off.

    On my prior BMW I used it to power both my phone and my GPS and no issues. Current bike already used for GPS so I use a circuit of from my HEX EzCan to power my phone. The Hex EzCan draws power direct from the battery and just "listens" to the CANBUS to power on and off and perform other functions.

    Others will just wire direct to battery but at minimum I would recommend some sort of power distribution box with fuses to allow a single connection to the battery and expansion of other power items such as heated gear and more in the future as keeps the wiring and setup much cleaner. You can also get a power distribution box that will use a relay to power off and on if needed.

    Just so i understand...if I have the OEM wired GPS mount on my bike, and I'm not using a dedicated GPS, I can cut into those wires to directly wire my phone mount without having Canbus get angry at me?

    Let's say your home has an alarm system with a motion detector. The alarm system uses the phone line to alert the monitoring service. Everything works fine. Then you get a dog. Now the dog sets off the alarm and the alarm monitoring company needlessly goes into its response protocol repeatedly.

    Does it makes sense to go on the internet and say "My new dog triggers the alarm and the alarm monitoring service goes nuts" and to have as a response "Yeah, it's the phone line"?
