I am looking to buy a sat-nav for the car and would like one that detects all cameras as well. Have looked at the Navigon Bluemedia PNA150, Halfords have it under the Medion label at £280 also been looking at the Navman 510. I would like one that doesn't need me to pay for updates. I know the Navigon one after 6 months you have to pay £30 a year for any updates. What about the Hard disk Sat-Navs, do you have to pay or can you just download the updates free of charge? if anyone has any ideas or recommendations I would be very grateful.
