I have a BCT15 hooked up to an old GPS unit. For the most part it works ok. However, every once in a while it locks out a group for a location that I am in. It will lock it out for maybe twenty seconds then unlocks it again. If I am near a POI it still shows the distance to the POI pretty close and continues to move further / closer to the POI. Is it possible that the GPS is sending a bad data burst then straiting it out again?
