Hi Folks.......Snoopy-C currently has a Garmin 180 gps unit with micro-g chips. I was preparing to get set up for some of the Puget Sound treks planned by the C-Brats, and I was unfortunate enough to find out that as of 12/04 Garmin "no longer supports G or micro-G chips" :sad :thdown :evil: . Therefore, unless I can find a used chip, my gps can't be detailed with the chip. What is a cost effective way to go? Obsolete great working electronics are the pits. Also, it appears some of the newer electronic maps have more extensive coverage than the garmin g/micro-g stuff. Suggestions please! Thank you, Ron
