Yeah, I managed to get one of the Carlin ones next day for £130 on Amazon, but they've shot back up to £160. Works really well though

Its a version 2.0 which apparently is quicker at connecting and no issues working with steering wheel controls as others have reported on other makes. No delay in phone call audio either. Only delay is when you skip a track, the image and info changes straight away, but audio takes maybe 1-2 seconds. But then it does that with the wire anyway. Not sure if its just Spottily though, as I don't use the Apple Music app these days.
CarPlay2Air also do one currently at £100, but their customer service is beyond shocking. I paid for DHL Express shipping that said 2-3 days. Nothing suggested it was coming from outside Europe. 3 days later I get an email saying it's been shipped via 'Shipped from China' so I queried why I paid extra for DHL Express. The question was ignored and I was effectively told 'because of Covid' it may take a few days to be delivered.
2 weeks later it still hadn't left Shenzhen and was now showing as 'returned to sender'. My questions of to why it was not being sent DHL express (despite paying more for that), was still ignored and I was told that delivery was taking longer due to Covid-19. Opened a dispute on PayPal as they were not answering my questions, so was emailed saying they would now only respond through PayPal. Now nearly 4 weeks later still no response of any sort on PayPal and I've had to escalate to PayPal themselves to investigate
I've since discovered that the CarPlay2Air is a copy of the Carlin one too. Should of researched more, but there are YouTube videos from independent people saying the CarPlay2Air does work.
