I upgraded from a KLN to a 430W not long ago. While I have had no issues in the first 10-20 hours, I had 2 complete dropouts (wihin 15 minutes of each other) enroute to Asheville a week ago. They were both complete failures, dropping to dead reckoning mode for about 5 minutes each. I had 3 other GPS's onboard and neither experienced the failure.
The 430 just came back from Garmin doing the Waas upgrade and included a new antenna. The antenna is mounted on a shelf under the cowl, where I have my other GPS antennae, which have never experienced a signal loss. I once got a RAIM warning on the KLN during an approach, but that is to be expected occasionally on the the non-waas units.
I am looking for some guidance with this. Clearly it wasn't a lack of sat signal, as the other units worked. I am wondering if this could be a problem with the unit or possibly with my antenna location. I am willing to move it to the top exterior, if necessary, but thought I would try the under cowl location to see if it worked. I do have 19' of cable coiled up under the panel. I suppose it could be a bad connection, but would have expected a failure in the prior 20 hours and higher vibration conditions.
Any thouights? Should I move the antenna up high? I need to rely upon this unit for GPS approaches.
