This has to be the worse camera detector on the market. Takes an age to locate a satellite. Subscriptions are expensive and you cannot update on any computer with windows vista or newer. Road angel are not going to produce software to suit the modern programmes so they expect you to buy a new unit. What a swizz ! The laser sensor which costs an extra £50 never picks up mobile cameras so is pointless. I recently brought a brand new road angel compact on e-bay which was seven years old but never used[security seal was still intact].After 4 weeks I did the first update and ever since it repeats the warnings up to 10 times and drives me mad. Road angel says it is nothing to do with the update but will fix at a cost [just leave the cheque blank] Do not waste your money. Try a cheetah or snooper.
