Here we go again with' mapsettings.cfg'

I installed UKandIreland 890.4222 map along with all my poi's and safety cams etc and all is ok.

I firstly created a dummy favourite to create mapsetting,cfg file with the map file and everything is still ok searching for addresse's and post codes etc. And when using the device just as switched on, the safety cam warnings still work while driving.

But as soon as I paste my old mapsetting.cfg file to the map, this is when things go wrong, all though the map works, and will load a favourite destination etc from my favourites list. But if I want to navigate/search to a new address or post code. The device will freeze and restart.

I have tried the other method where I add my mapsetting.cfg file first and then via TT Home, operate my device then try to add another random address/post code. But Home tells me I cannot use this map on this device.

Any clues what the problem maybe

How about you finally start reading the tutorials?
The procedure to repair a mapsettings.cfg is quite different from what you are trying ;)
Any why Home is complaining should be well known to you by now as well ;)
