Soundracer V12

The Soundracer V12 is the worst-built product here, and although it plugs into your 12-volt socket, there’s no cable or USB output to charge your player. When we connected a 3.5mm cable to our iPod, it broadcast our music quietly and with too much interference. There are no presets and its range is limited, with frequencies available from 88.1FM, not 87.6FM like many rivals.
