I bought a Road Angel Pure. The first one didn't work and I got a refund from Amazon. I tried the buy a new one from Car Audio but they were uninterested in offering real help. This annoyed me as I was already paying a subscription for the road angel with Car Audio and they did not accept any responsibility. I was forced to buy another one at increased and further cost (ie more than the refund) and Car Audio supplied me with a 'refurbished' (ie second hand ) model. Despite their reassurance that this works and was 'as good as new' when I got it it would not charge and I had to send it back to them. That was 2 weeks ago and I have heard nothing since. My expensive subscription to updates has not been refunded at all. Shocking unhelpful service in my honest opinion.
