Dash board off! on 2002 Acura MDX

All of the meters (gas, miles reader, engine light, etc) went off on my panel. Someone was upgrading my radio to a GPS system and now they dash wont go back on!! Any suggestions of what it might be? Everything seems to be ok when tested, so it is not burned or a fussil nor anything like that... Help is appreciated

Take it back to who ever was 'upgrading' your GPS, obviously the up grade did not pan out.
