We recently had a customer visit with a faulty head unit, which turned out to be a failed hard drive inside the unit. At dealer a new head unit would have cost in excess of £2,000 We replaced the hard drive with a brand new drive, updated the software on the unit, ensured that the owner had the latest 2022 navigation maps and Gracenote database for a fraction of dealer costs. If your BMW head unit or any other electronics are faulty, or not behaving as you’d expect then get in contact.
