Sounds like the folks who installed ur tow bar has done/removed something in the fuse box, and has now affected ur Infotainment.

 

"Open Circuit" means either a fuse or wire plug is no longer connected.  The car electrics is expecting it to b there, but nothing.

The strange thing is the socket will still charge my phone but it wont register a usb memory stick or android auto

wat model year do u have @tom500?

do u have just the one usb port under the climate control?

or do u have another inside the centre arm rest storage area?

At a guess, the fakra connector for the USB socket isn't correctly attached.

 

They probably removed the headunit for better access to the fuse box. The USB socket uses a fakra for power/data but there is also a second power feed to allow for faster charging etc which ties in with your symptoms assuming the first isn't connected

Do you mean on the back of the media unit in the glove box, Or have I named it incorrectly lol. I removed the unit in the glove box and  I didn't see any lose connectors . Has any one got a pic of the fore mentioned connector attached to the media unit? 

Yup, on the back of the unit in the glove box. I think it's probably the yellow fakra IIRC.

 

I can't see any reason for them to have disturbed the connector below the climate panel 😕

 

Might be worth contacting the fitter and asking them to check for you?

Yeah its going in on Friday morning for them to have a look. As you can see below all cables look connected.  Things are also connected at the cigarette socket end as well 

Just an update on this, Skoda dealers couldn't find any issues. So I replaced the usb socket and all is working  100% again
