The product was sent fast and i have yet to open the instruction book - I plugged it in and charged it - switched it on and set the thing up in 60 seconds flat - However, if you dont subscribe for the updates then it will have limited use - I paid for the updates, regestered my machine online ( about 2 mins the lot ) and within 4 hours it had registered with my road angel and away i went. Simple, clear and just what i wanted to help me on my way. The only real issue is that ive got a convertable and with the lid off you can barely hear it talking to you and beeping. If it was twice as loud it would be perfect - Still, i am so pleased with it and it has picked up 2 x vans so far !! THANK YOU !
