The FM tuner of the Shaker 500 audio system of my 2005 GT convertible only stops at stations with odd decimals, e.g. 101.1, 101.3, 101.5 and so on. Here in the UK we have stations with even decimals. e.g. 100.2, 100.4, 100.6 and so on. Is there a fix that would enable me to tune to "even" stations? Thanks guys!
