Plotter problems...

We replaced our chart plotter earlier this year from the Raymarine A70 to a C70.  progressively more it kept crashing. Last thing you want from a chart plotter. It kept saying 'Improper Cartridge Removal' even when we hadn't touched the cartridge. To start with we thought it was something we were doing wrong with the cartridge, and talked to our local Raymarine dealer from whom we bought it.

Eventually we came to the conclusion there was something wrong so removed it today and took it back to the dealer for him to look at it. I (Richard) am away for a month in the UK, since my son is getting married so it's a good time for this.
