Lots of stuff these days has remotes. So you could just put the remote in the back seat. Don't really need it up front. But if you want one in both places, buy a second one.
...Or you might check to see if your car stereo has Bluetooth remote control capability, in which case you might be able to control it with a smartphone app.
