Well like I’ve said before, I’m new to this aircraft ownership thing….  I have a Garmin 430waas and was wondering when do you send your 430 out for service? “If it ant broke don’t fix it” type of service? Or is there a general rule or time frame I should send mine out? Yes, it has been working fine but I did have a day last week where it lost GPS signal a couple times. It did regain signal and was fine for the rest of the flight.  All thoughts are welcome—
