try disconnecting your deck and then re connecting it. also reset ecu. this helped mine, i had shity connections with loose wires. same thing happened when i put my alarm in, had wire pull out of connecter. i would check all wires/wiring of stuff you have or had someone install in the car.

 

Code 20 is for the Electric Load Detector. Pretty common problem. See http://search.yahoo.com/search;_ylt=...myy&fr2=sb-top
