I've got a 2021 M340i. I know I don't have HK and I also don't have tweeters in the doors. So did I get the lowest level audio? I would like more volume and sound quality. What would be a decent upgrade without breaking the bank? Vin decoder shows the entertainment system attached.

The system is called "Stereo" by BMW (no tweeters). It will not show up in the VIN decoder.

So is this the lowest grade radio available? Is there a relatively inexpensive way to upgrade? Relative means under $1000.

This is the lowest of the lowest BMW audio systems.

If your G20 has iDrive7 then try this : https://www.ebay.com/itm/23377476036...mis&media=COPY

Start with a $900 shipped to the USA offer… it may work.

Thanks. Looks good. I’ve had my eye on that.
