Hi All,
Felt very smug when the mast was raised, no huge tangles and all looked fine. That soon dissipated when I re-installed the batteries to discover that the GNX wireless instrument is not being recognised on the chart plotter - worked fine during the first season. I did not store it in a box over the winter and it was sat on a shelf that would get daylight, but not direct sunlight. Garmin assure me that it is un-likely to be anything to do with connections on the mast or at its foot and the first option is to replace the re-chargeable battery which I will attempt once it stops raining and the wind reduces. Just wondering if anyone else has had a similar experience with a BC23 and can offer any more possible causes of the issue. Thanks.
