PIONEER INNO 6 months after getting my PIoneer Inno, my remote quit working. My thought was dead battery. I replaced the battery and it is still not working and I can't find anything in the manual to help

I've had my Inno for a couple of years, and haven't had any problems with the remote, until now.
However, since I have two other new 'in the wrapper' remotes, I pulled one of them out, and still can't get a response with my radio.
So, I'm thinking it is a problem with the radio itself.

Mine didn't work out of the box either -- but i discovered if i warmed the remote up ---it works fine. I put it in front of a heater vent till it gets warm then it works great --- as long as it doesn't cool off.
