I have a Garmin 5212 and a 4208 chart plotter on the same network. I downloaded the software update from Garmin's website onto an SD card. When I loaded the update onto the 5212, it appeared to load the 4208 software onto the 5212. It appeared to load the 4208 with the 5212 software.
Now I don't get a GPS signal, hence no location, no speed. I do have my sounder information though. I've tried reloading the update and resetting to the factory settings. Nothing has worked.
Any thoughts? Your help is GREATLY appreciated.
