I drive a Prius 1 in the UK - it is a direct Japanese import and the FM band goes from 76 - 9o mHz, a bit of the problem in the UK, where the bandwidth is 87.5 - 108 mHz. Both franchised and non-franchised dealers Toyota here have been little use, warning of problems with after-sales fitting, and suggesting car audio specialists... I need to modify the radio - any ideas please? Thanks!
