Hi All,

I received my new Garmin last Friday and did the first test on the boat last weekend.

Works as specified, screen is ok, pre-loaded bluecharts for UK/Ireland are very detailled (Dublin area so far /forums/images/graemlins/wink.gif)

The reason why I bought it, was the possibility to save my tracks, waypoint etc. on an SD card, take it home and do the work on my home PC.
The 'save' point works fine, I can see the files on my home PC...but: what file format uses Garmin? There is an .xml-file which contains information about the GPS itself (Software, Unit etc.) and an userdata.adm file.
This file must contain tracks, waypoint and so on.
Which programm can I use to access the data?
I have an Bluechart-Version for the PC (2 years old) but this can't open the file.
Is there a conversion programme available or do I have to buy a brand new version of bluechart now?

Any help appreciated,
jow
