hi all. I have a friend who sends me rides from basecamp which I install onto my gps.\noccasionally I hit a detour , closed road, or whatever. the ride has way points listed.\nonce I go off the route, the gps gets all goofy , tells me to make u turn and will not put me back on the ride after the detour.\nso essentially I have to end the ride . \nis there any gps that will recalculate around the detour and pick up the ride again ? I see there are several units from 200.00 up to 900.00 dollars, but none of them shows it will recalculate. if I start the route over, the gps will take me back to the home point which sucks if I am 3 hours into an eight hour route.\n\nhe has an old zumo 500 which never seems to give him a problem. he told me not use the detailed road route, but just follow the non detailed map which doesn't offer any info as where to turn or distance , just a pink line showing where to go.\n\nthanks for any help offered.
