Hey all, has anyone found a way I to the engineering menu for the S5 infotainment unit? I have a trophy I picked up on Thursday and while overall I'm happy, the built in data connection seems to be stuck on 2g. The car I test drove in the same area had 4g so I wanted to take a look and see if some form of activation or toggle was missed during commissioning.
I am also a big nerd and software developer so seeing a little under the digital hood would tickle me too! I have found where I think the entry point is (tapping the version under settings multiple times) but I don't know the password. Another thing which could be useful is if someone has the service manual for the car as it should say in there what to do.

Thanks
