Have you loaded CNE NTU ? NTU gives search problems in old units
I've tried to search around for a few hours, found some people asking the same question but not a single person that managed to resolve this issue.
The Garmin Nuvi 765t errors out with "Cannot calculate the route." on all requests. It starts calculating and then around 80%-99% it throws up the error. Every time.
I originally had 4.00 I think and updated to 4.30, but at the same time I also put in 2012.20 maps.
I've tried many things and wonders if anyone her would have any tips?
I've tried to:
Revert firmware to 4.30, 4.20, 4.00, 3.90, 3.60 and 3.40
Reset by holding bottom right corner at boot.
Delete the GPXs
Loading maps: 2012.30, 2012.20, 2012.10 and 2011.40
Loaded Basemap: Worldwide autoroute DEM Basemap NR 5.00 and Worldwide autoroute DEM Basemap NR 3.00
Enable and Disable Bluetooth
Bunch of other things I can't remember
Unit is out of warranty so it would suck to have to throw it away.
Any suggestions would be appreciated !
Maps I've tried
CNE NT 2012.10
CNNA NT 2011.40
CNNA NT 2012.10
CNNA NT 2012.30
USA-HAWAII NT 2012.20
USA-HAWAII NT 2012.30
All have been unlocked images just dropped in. No messing with mapsource.
Issue started after I updated FW from 4.00 > 4.30 and updated the maps. Two of the maps worked perfectly fine prior to the updates !
I downloaded the rest of the maps to see if it was a map specific issue.
Any other pointers? :-)
I tried deleting all maps of the device.
Installed Mapsource and used: "City Navigator North America NT 2012.30 MapSource"
Sent to device a tiny region in my area.
Still get "Cannot calculate the route."
Running out of options, anyone have any suggestions please?
Aaaaah desperate... any suggestions please?
In its current form the device is a paperweight. Sucks.
To anyone else out there, if it is working perfectly for you already then _DO NOT UPDATE_ unless you really need it.
I stupidly had a 'update' twitch, of course I had to install it. Now a useless block of plastic with the warranty expired 1 month ago.
Hi, and thanks for your suggestion.
But as mentioned in the original post, I've already tried many older FW.
"I've tried to:
Revert firmware to 4.30, 4.20, 4.00, 3.90, 3.60 and 3.40"
Even tried to re-upgrade and re-downgrade. No difference, still get cannot calculate route on all searches.
Any other ideas? :-)
Do you fully delete all old and other maps before loading new?
Love your wife? Buy yourself a GPS for answering to her favorite question: "Dear, where are you?".
I think so.
Do you know which files are 'critical' to stay on the device?.
I'd very much like to completely purge anything on there and put it back to factory defaults but I'm not sure what can be deleted !
There are no 'critical' maps. Delete them all.
