thanks for the useful advice lol i travel all over the country opening safes, like today been to Ealing and weybridge, now it would of been a nightmare to find both places so sometimes they take the stress out of travelling !!!!
I want to recommend another option. My HTC mobile has a navigation app ( Android) which is as good as the sat nav in my co car. Set the destination, put the ear piece in, lid on and go. Free too. Recharge the phone as or when.
It was worth the money I spent on the phone for this alone!!
It may be a control thing but I admit I often plan a route by map rather than rely on the sat nav. Not anout trust, just hate being drip fed the info, I want to know roughly how far, how long, where im heading to get my head in the game.
