Super easy to install this! It might be best to add another rubber plug so one can really plug and play this through the trunk instead of mounting the controller at the bottom of the car. I installed it in the trunk myself and was done in 15 minutes.
Works very well!
Die Steuerung war einfach zu verbauen und funktioniert tadellos. Versand ging ebenso fix. Kaufgrund war für mich die 50%ige Ansteuerung und der günstigere Preis im Gegensatz zur Konkurrenz. Bin absolut zufrieden.
After I ordered the controller, it arrived quite quickly. The installation is very easy. Plug and Play. I drove the car in the garage at home on a few blocks to get under it better. In a little over an hour I had everything installed and finished. Works fine. The sound has really become significantly better. I have a BMW M3 competition Touring from 2023. The sound is fuller and deeper. Now I also have a nice sound in the exhaust in the normal driving modes. I am very satisfied so far.
