I presented these guys with a bit of a challenge regarding the DAB reception in my Lotus (Glass fibre and composite, etc). The last thing I wanted was a hole to be drilled in the car for a replacement antenna, and, thankfully, they were dead set against that too.
Tried a couple of options and cable runs before getting it right, but now I am delighted with the final result. Have to admire their patience and determination to get it sorted. Updated the firmware on my head unit while they were at it, all part of the service.
No hesitation in going back here for all my future car audio upgrades.
