How to change "KDC 215s" tuner in US-model to Euro

[Audio-plus]

Hi,

Problem is that the tuner is US-model so it steps only 0.2 MHz steps I can't listen to frequencies that are even (e.g. 107.6 MHz) - only odd ones.
Is there any way to change it work with 0.1MHz steps ( easter egg ? )
I don't want to buy a new reciver

Thanks a lot!
