Considering that a major avionics upgrade could outprice the aircraft, it makes sense to consider repairing—instead of replacing—your existing equipment. While this might seem like a good short-term solution, you might be throwing good money after bad.

The repair versus upgrade decision might depend on your mission and whether the unit will be used for primary or backup. Consider three questions: How much does a like-exchange cost? How much serious IFR do you fly? Does the manufacturer still support the equipment? Be careful of using the excuse that you might sell the aircraft soon—selling with old radios works in the buyer’s favor.
