Disorganised ordering with fitting at Halfords. Link provided to Halfords didn’t work, once sorted there were no booking slots, can’t call local store so visited to be told they only fit Halfords sold units, once that sorted Halfords then needed car to inspect for suitability first before booking the fitting at a second visit. Instead went with mobile fitting service outsourced to RS Connect which was more expensive but they did a good job (so extra star). No user manual for the unit purchased, RoadAngel advised it not written yet. They provided a draft version which had couple useful bits but clearly short of decent quality.
