Finding my mmi version

Good evening all. I think I've found the mmi level I have ... It's mmi basic plus 2g as I have speakers in the rear along with DSP. It's a red display too. I'm trying to find what firmware level I have before I go and fit a dab module to it. I held down setup and return for a few seconds where it only gives me the option to update my software. I can't find any software version . Can anyone help please. And also ...will it automatically be in the waveband section once plugged in ?
