Arghh I love my sat nav but in the last month or so it's pretty much broken, I've had it about 11 months and don't want to have to get a new one
I have the nuvi 310 and whilst driving one day it lost all satellite reception - I've tried (as it says in the instructions) to take it somewhere where there are no tall buildings/trees to regain reception and it hasn't, I've also updated it with new software and it still doesn't work
All it does it leave a big question mark on the map.
Garmin handbook is not very helpful in this problem!
My unit 660 is very slow to upload map these days, the same question mark on the screen. Mine is kept well, no damage, so I guess the unit might be old.
