Fitment

Soundtech does not list model years for this package. If you are not sure your car matches, send us the VIN or build date and we will check before you order.

Which BMW sound system do I have?

Soundtech groups its BMW packages by generation and factory sound system. This one is for G generation cars with the RAM (radio amplifier module) system, which Soundtech says came in around 2019 to 2020.

Check your VIN build sheet for option code S0676 (HiFi speaker system) or S0688 (Harman Kardon surround sound). If neither code shows, it is usually the base stereo. Send us the VIN if you want us to check.

Installation and tuning

Soundtech lists its plug and play packages mainly for dealer and professional installation, although MATCH based packages can suit a confident DIY installer. The MATCH UP 8DSP MK2 is a DSP amplifier, so it needs setting up for the car once it is fitted.

Warranty

Soundtech, the Australian distributor, gives its products a standard 12 month Australian warranty. That is on top of your rights under the Australian Consumer Law.
