So trying to find out which sound system I have on my 2013 l494 - I have front meridian door speakers, tweeters and rear door meridian speakers and speakers next to the parcel shelf but I have little or no bass/sun noise .
My audio settings seem to be stuck on stereo even though I have the 3 meridian surround sound options but it won’t select them when I press on them? The car has had low battery issues as it was sat for 3 weeks prior to me collecting - I’m not getting a low battery error anymore after doing a few runs.
Attached a pic below of my screen…
