Radar Detector turns off when engine stops
Hey guys,
Just picked up my new 2012 535i and loving it so far. Carbon Black w/ the M sport package I hardwired in my Valentine this weekend and used the green/brown wire that heads towards the rearview mirror as was suggested in a few posts on here. This works wonderfully when turning the car to accessory and when starting and turning off the engine via the ignition. However, when the auto start/stop turns the car off at a stop light the detector also turns off and fires back up when the engine starts. While I realize I have little to worry about being clocked w/ the engine off sitting at a traffic light its a little annoying having the V1 come back on every time the engine restarts. Do you guys have any ideas if this is a voltage drop on the wire? Thanks |

You need a V1 accessory called Bob the brown-out booster:
Maintains power to V1 during engine restarts. Installs in line between V1 and the 12-V power source. Includes 3-inch power cord and two selfstick interlocking fasteners. Available on the V1 website for $25. |

Oddly enough, when the auto start/stop turns the engine off it doesn't always turn the detector off so I'm assuming the source varies depending on specific conditions. I thought it was headlights on at first but that doesn't seem to be the case. |
