    Default GPSMAP 4210 with Bluechart/firmware question

    I have firmware 7.30 and would like to upgrade it to 7.80, the current upgrade on Garmins site. Do I run any chance of making my current maps, both purchased and downloaded and unlocked with gimgunlock 0.03 unusable by doing the upgrade?

    This chartplotter was fairly recently retired I'm told and that the new touchscreen models are running 8.0+ firmware. Not sure if the numbers correlate or not.

    BTW, this is our primary navigation for our boat/home currently in French Polynesia, so we really don't want to screw anything up we can't recover from.

    Thanks for any assistance or direction.

    For those who are interested. I went ahead and did the firmware upgrade yesterday to both units and all went fine. The v 17.00 Polynesisa Vision Bluechart I have works fine. No problems and it solved the issue we have had with the plotters since purchasing them. This chart was downloaded here and unlocked with gimgunlock 0.3 for mac.

    Just wanted to pass this along for anyone else in the same boat.
