Ordered 6 for my taxis. Can I say very pleassed with the purchase, they work perfect through our taxi car radios. The sound quality is exactly the same as the radio itself.
The call receivers can hear us clearly with no problems. I was worried about this but this sytem has two microphones, so the voice pickup is great. I did try a cheaper system first but it was useless so dont waste your money.
The caller id on the mirror is also just great, no more seeking or looking at the phone now. It download all my contacts from my phone.
There are loads more features which i need to try but this blueetooth mirror is Highly recommended
