Installed the module in my 9A as many have done, behind the aft baggage bulkhead, hanging in free space under the canopy rail. After calibration, I had over 20 degrees of misalignment. A call to Mike at Dynon was very informative. Great support from this excellent company. We discussed the possible causes, and determined that it must be ferrous interference of some kind. Then...while getting ready to do the compass calibration...I thought about the canopy rail interfering with the calibration when it was slid open. Bottom line, make sure the canopy is closed when you swing the module if you have a similar installation as mine. You can watch the compass heading increase as you slide the canopy rearward, but by the time the lid is 2/3rds closed, there is no more deflection. I will most likely move the module 1 bulkhead rearward to minimize risk of ferrous items in the baggage bay from affecting the heading. Short flight last night showed headings where they should be in all directions.
Just some feedback I hope will help.
