I think Giomen is on to something there, the GPSMAP 276c is not in the compatible devices list for BlueChart g2
But the author is interesting to it and BCh limitation for his Nuvi is suited for him. I doubt what BCh is compatible with Nuvi. Why do not try use G2 for 276C. It works on GPSMAP 60-78. Not so good but it is work after map menu manipulations.
Garmin, how much is 30 pieces of silver for Judas today? Were they worthy for crucifix of GPSPower?
