When I experimented with the suction-cup mount to find the best placement in my Cessna 150, I discovered the no matter where I placed the iFly 700, (even in my lap), I was getting a 30 degree deflection on my magnetic compass when I powered up the iFly. As I know that other moving map GPS units are panel mounted right below the compass, I am wondering why my unit causes this behavior and what I should do about. First though of some shielding will likely effect satellite reception. Please help with some i nstallation suggestions / instructions.
