Garmin GNC 300XL IFR/COM GPS

[Alan Williams]

Had one in my last aircraft. Excellent com radio and nav receiver. Had no problems with either and would characterize them as being strong equipment.
Have a 430 now and found the 300xl slightly easier to understand and then operate the various pages and groups.
Did not use the 300 for approaches so cannot really compare for you but I'm sure others can.
