Need to reassign GPS switch

I installed Malaysk's Feb rom on my Joying HU. That went fine and everything seems to work fine. After I installed the rom, the Sygic app was erased from the SD card and my hard GPS button remapped itself to the radio app. I then installed Igo from Joying and now the hard GPS button is mapped to Jet Audio.

What do I need to do to remap the hard button to the GPS app?

I do not have Exposed enabled, is that what I need to do?
