TomTom - again...best mapping and easiest navigation I've yet used...now with more maps and upgrades available.
I bought my Dad a cheap one so he could find his way here (to my place in Germany) and he's still raving about it...
After two years my Go-720 has developed a minor, intermittent fault and even though it's out-of-warranty, they're fixing it for free...
In extreme heat, the screen stops working after a couple of hours' operation, though it's fine at anything below 35C - I think it started after it got left in the car *once* overnight last winter when the temps went down to -27C here in Germany for a short while...
The unit keeps navigating, but I had to let it cool off before inputting more instructions - it's only happened twice, but as I say, they're fixing it for free...
