E7D problems

[Mark maulden]

My system:
-E7D with recall work performed. Not the latest software but somewhere close. Not sure i want to update.
-SpX5 pilot. Updated approx a yr ago. Cannot recal the compass. Worked fine before. Why cant you move the lookup tables to card and then reinsert after update?
-HD color radar. Working as long as plotter works
-AIS650 working as long as plotter works
-Standard horizon radio with NMEA connected. It works

The touchscreen on this plotter is not working right. My plotter freezes up when I attempt to change things either touchscreen or rotary knob. It gets to where nothing wakes it up. Submenus appear without being called up. When i rotate the knob to zoom in or out it sometimes goes full in or out. The cursor takes off on its own and keeps going. I had it commanding the pilot to got to cursor and twice it fell asleep offcourse and no alarms of XTE. Using chart and radar on split screen really confuses it. I've had intermittent problems since i got it back from recall.
