Have been getting problems aring and re-arming my Subaru system

But this only happens at a few locations around the town centre ... Could it be radio waves "blocking" the signal as it seems to happen when in sight of a certain radio mast

Has anyone else suffered this or should i get it checked out

Check out the "subaru immobiliser" thread below. The two are related!

 

Fire Station blocks mine. Bottom corner of the windscreen, drivers side works in the end.
