Which towbar Volvo XC60

Swislon

Hi, we picked up a used XC60 D4 2013 a few weeks ago and need a towbar. 1.The local Volvo dealer fits a Brink detachable or fixed. Does anyone know how the breaking cable fits to the Brink detachable? The last detachable I had on a Honda CRV didn't have
a hole big enough to allow the braking cable clip to pass through so we ended up looping round the ball. However this is not recommended on a detachable! 2. I obviously want the Volvo loom fitted and could get a bar fitted at our local Towbar garage rather
than the dealer. Does anyone know whether they can also  download the software to link car and caravan in sync?
