Does anyone know if there is anything I can do about My Landrover Beker sat nav radio I can only tune it to odd numbered stations ie 98.5 but not 95.8 help!!!

Not a fix but my mates got the same problem in his P38 radio.
Tried all sorts of stuff to fix it and he's now looking for a replacement unit.
Seems the digital tuning chip inside has decided that only odd numbers exist.
Could try a specialist to investigate but sounds like a replacement if his experiences are anything to go by.
Sorry.
