I have a Superb Estate 4x4 MK2 2013. The Bluetooth receiver under the passenger seat has stopped working. Does anyone know if I can upgrade a replacement or just replace with the same spec?

Hi, welcome.

This is the 'Hellos & Goodbye' forum, I'll 'Report' (drop-down on the three-dots at top right of posts) so that a Moderator can move your post to the Superb Mk2 forums of the 'Škoda Superb' section of this site where there will be owners and others with lots of information and advice on your model.

Good luck.
