I use a Garmin eTrex Vista HCX with City Navigator. Works good most of the time. But not at all for route files generated off unit. Always corrupted. No problem with track files.
Would like to hear from folks using the Edge 705/800. The good, the bad, the ugly. I'm especially interested in how it handles a route file built at an online mapping site and transferred thru Mapsouce/Basecamp. Garmin says the Edge will not corrupt the file. What's your experience been? Are turn by turn directions reliable with transferred route files? What's your evaluation of the utility of the touchscreen? Of the Edge models for cycle touring?
If good responses, I may reference this thread in an article over at CG.
