I have the base model 2010 Insight with the factory radio still installed. The step size for the tuner is 200 kHz (so I can pick up 88.9, 99.1, 99.3, etc.), which is fine in the US. Unfortunately, I'm driving it in Middle East, where the radio stations aren't that restricted, so I'm missing at least half of the stations. Is there a way to reduce the step size for finer tuning?
