stereo mic input to mono mic connector

I have an issue with using the mic on a 2012 toyota RAV4 with aftermarket head unit. The head unit has a mono-input for the mic. The vehicle has a built-in overhead mic that I want to use with the head unit (if possible). The issue is the mic on the head unit is mono and the vehicle has stereo input (L/R).

My question is should I wire the L+R leads coming from the vehicle mic and wire both together to the mono mic audio input?

Inside the sheathing of the mono wire you'll probably find foil or maybe braiding wrapped around 1 or 2 wires. The foil or braid is the shielding and sometimes also is the negative, so if inside you only have 1 wire the shielding is the other. In a stereo wire will be 2 wires besides. You can connect those 2 from the source to give you mono output.
