Updating garmin 430w
I have it mounted right next to my Garmin 430W antenna, which I know Garmin warns against, but up until this point I haven't had an issue.I tried to move the culprit antenna further away from the 430W antenna, but I still had a lot of interference even at a couple feet away!GNC 420W seamlessly integrates built-in terrain and navigation databases, providing a clear, concise picture of where you are and where you’re heading.The 420W's huge Jeppesen® database, updated with front-loading data cards, contains location reference for all airports, VORs, NDBs, Intersections, Flight Service Stations, published approaches, SIDs/STARs, Special Use Airspace and geopolitical boundaries. obstacles databases, the 420W displays color coding to graphically alert you when proximity conflicts loom ahead.
The first thing I noticed was the signal strength for the satellites the 430W was picking up were quite weak.
I went flying last weekend and when I was turning crosswind, my Garmin 430W indicated the "Loss of GPS navigation - Dead Reckoning" message.
I usually see this when I bank too much in a turn, so I assumed this was the case here. A few minutes later I noticed my GPS location was not updating and the 430W still did not have valid GPS signals.
It reminded me of my first Magellan GPS 300 I had for my boat (too about 30 minutes to lock onto GPS).
I checked the cabled ends to the antenna and the GPS unit and all looked fine.
