Garmin Gmap cartridge

[fiddle]

When i bought the boat she had a Garmin 235. The cartridges for these things are rather expensive, but I bought one for my home waters and Im happy with it, except for the fact that my homewaters (Nort Wales) is right on the join of two cartridges so I need to buy another. Thing is Garmin have changed this format, implying that they are not totally happy with it. I still have the cartridge for the South Coast which is currently redundant. Now, although I am likely to use my laptop with probably SeaPro software, it would be sensible to have the Garmin as a backup. Has anyone explored the technical aspects of rewriting a Gmap cartridge with data for another area? and is the data flowing around somewhere on the web?

You can have new charts written to cartridges, or updates of older versions. This is a service offered by Garmin and their agents. There have been so many changes in large chandler ownership lately that I'm not sure who remains, but we last had an update last summer by Cruisermart, or whoever it was who answered their previous phone number.

Although G-charts are described as obsolete there are millions of them in service. The software is not Garmin's, it was Navionics but changed to someone else last year. It seems to me that this will be available for a long time to come. Hope so, anyway, as I have quite a lot of them.
