I have never had a car-tuner where this option was really working. We have many radio-stations here around, the french over the boarder are boosting their programms with some extra-power. The LOCAL setting should prefer stations in the direct area, so they won't get disturbed by the stronger, but more far away ones. But not my Kenwood, nor my two Sonys did make a hearable difference between LOCAL and DISTANCE, so i think let's forget this feature....
