Garmin GPSmap62 Series with IGN maps in France
Q. Does your answer ref using IGN maps in France with Etrex Vista apply to the GPSmap62 series of products?
Geoff Gurling, Hessle
A. The Garmin GPSMAP62 is a Handheld GPS Navigator. I am not familiar with it but it seems likely that the datum it should be set to will depend on which maps you have with you - either in the unit or the paper version.
NB. See How do I set my GPS for walking in France for the original question/answer Geoff is referring to.
