The IHD is a waste of time, it hasnt worked from day 1. When the engineer fitted it he made some excuse about ‘syncing time’ and left quickly - Presume they get this all the time.
All bulb will do is send a reboot which does nothing. Mine has been rebooted 10x and still same issue (6 months in)
I would advise selling the unit on Ebay - its useless.
I have rebooted and informed them but nothing is ever done. Since the administration have taken over the running of the company the customer support has deteriorated.
