There’s been some buzz lately about some new GPS receivers that look like they’re going to replace the venerable GPSMap 60 and 76 series models. Garmin has so far confirmed a 78, the replacement for the 76. As of now, there are only just rumors about a replacement to the 60, a supposed 62. GPSFix has some informative posts worth reading if you’re interested in this sort of thing. There’s a post for the 78, and one for the expected 62.
I’m pretty interested in these, since I’m a longtime GPSMap 76 CSx user. I had mine rigged to my handlebars some years ago before I bought an Edge 705.
