Does anyone own a Canyon?

I've diagnosed the problem as being with the shifter, as when you hold down both FD shifter paddles to check the battery level there's no light on the junction box. Pulling out the cable at either end and plugging back in to get the 'click' doesn't solve the issue either.

Ah, I didn't realise pretty much every shop is set up for Di2 - I need somewhere east or in the City ideally. I stupidly thought you would need a shop that had the Shimano software (this is what Canyon told me anyway).
