Tony,
We bought Tom Tom 710? after going round Cardiff three times looking for Ikea when we were staging a house. Massive row in the car on the third attempt to find Ikea. Back seat driver daughter said " It's Tom Tom or a divorce!"
Very pleased with ours called Sally Traffic.
Only time it let us down was going back to the gite from supermarket in Cahors town. I pressed shortest route instead of fastest route out of curiosity
.
Big mistake. The road got smaller and smaller , more rutted gave out and finally we seemed to be driving on a sandy path. Luckily some pedestrians were near and ,saying we were lost, I asked them where we were. " Oh, madame, you are on the grande randonne 65 hiking trail"
Well I did press the wrong button....
