I`ve had TomTom sat navs since they first came out and over the years i`ve owned 4 models and then a NozaTec.
I`ve now had a Garmin Camper 760 LMT-D for the last 3 years and it`s by far the best one yet
The 7" screen is brilliant and navigating around it is much easier that the others.
Yes, it`s had a couple of " moments " but i ignore anything that doesn`t look right and it soon re-calculates.
The others ( even with the length, height and weight set ) got us in a right pickle a few times the worst ( NozaTec ) being a 7` bridge
My main gripe was that having spent all that money on it i needed to buy an extra 32GB micro SDHC card because the memory was virtually full after the initial update at purchase
Everything is automatically looked after by Garmin Express and our POI`s load very easily using the Garmin POI loader and the instructions found on here
The big 4 ( quarterly ) map updates take a while to do but i have a fast internet connection so its not too bad, simply connect and leave it to it.
Garmin UK support 0800 238 000 is probably the best customer services i`ve ever dealt with and nothing is too much trouble.
I`m sticking with it for a while yet and will definitely buy another / updated version of this model when the time comes
