Query: Works when it feels like it

This product is supposed to restore full functionality of steering wheel controls. How ever I noticed that it doesn't always work. Usually the next song button stops working or it magically changes into previous song for either of the buttons. The volume button always works that isn't an issue. The mode button also does crazy stuff where it sometimes turns the device on or off, other times it may just mute it while it is still on, other times it changes the function from USB to Radio etc... Strange! Not to pleased with this product when it isn't working (40% of the time) but happy when it is (60% of the time)
