SSV remote battery

I recently bought my first RZR, a used 2013 800S and there were a few things that needed repair. I’m now down to getting the stereo working. It came with a SSV overhead first-gen unit. No control buttons on the outside just a remote to control the unit.

Can someone tell me the correct battery to use in the remote? It had a CR2032 in it but that does not seem to activate the display on the remote. I realize the remote is probably bad but before I bought a new one I thought I would be sure I had the correct battery in it.

Thanks for the help!
