Thank you very much for detailed reply
Must admit I've always been a TomTom guy but have read good reports about Garmin
What I don't like about TomTom is they withdraw support far too early - I've got the TomTom 1005 Camper version but have had problems (along with a lot of other owners!!) after TomTom did a supposed upgrade
I realise and appreciate TomTom need to have a turn-over of sales but don't think they do in the correct way - they don't forewarn you of withdrawing support!!
Take care ALL
