Pioneer AVH-201EX vs. AVH-211EX

Hello,

I just received a Pioneer radio for my old car, and found the seller shipped an AVH-211EX model instead of the AVH-201EX that I ordered.  I've surfed the web and visited the manufacturer site, and found no difference in features between the two models; only the 201EX is a few bucks more expensive.  I would like to here some opinions to make a decision keeping the 211EX or returning.

Thanks, roreru
