Looks like I'll be hanging on to my 276c for the time being.
As far as I can see all they need to do is update the 276 derived models with a couple of extra features:
- Use standard SD cards, and have the ability to transfer tracks and routes to/from the card so there's no limit to your tracklog storage.
- internal aerial
- more up to date user interface.
The Zumo 550 does most of want I need, but I won't buy one cos the high-res screen on the 276 is so much better.
I like the idea of the large touch screen on the 640, but if they've removed a lot of the routing and tracklogging options then it's a case of one step forwards, three steps back.
I guess we'll have to wait until an independent reviewer gets their hands on one to find out the full spec.
KTM 990 rider and proud of it!!
950 adventure gone, but not forgotten.
