Hi Rudiger,
I bought my unit from the UK and had it shipped to Malaysia. I am using the Navionics version 1.8.8.0 charts for West Asia, being Malaysia, SIngapore, Thailand etc which update fine.
I am based on a small island 2 miles x 1 mile and have 16 odd waypoints for dive sites, but both the boat and the waypoints on the East coast appear to be on the island. So I am positioned on the waypoint 200 metres offshore, but the display shows me and the waypoint on the island.
This is duplicated on the lake in Kuala Lumpur, I am on the water but the display shows me to be on the land adjacent to the water.
The reason I am trying resolve this I need to map the seabed with the sidescan and need to know that I am getting accurate GPS fixes before I convert the files for use with Garmin Mapsource. This will allow me to print a map of the seabed.
Many thanks,
Guy
