This month, we travelled to the South West city of Bristol to test its retailers on their knowledge of the Sat Nav market.
In the second part, we test the city’s specialist retailers – Currys, Maplins, PC World and Comet. On Friday, we brought you the results of the non-specialists, which included Asda, Tesco Homeplus and John Lewis.
