OK, a five star review. Now most of you will be sceptical, I would, but honestly I didn't think it would work never mind be so good.
I unpacked this item and foolishly threw the instructions away with the packaging, but I remembered something about pairing it to the car and then the phone, anyway I fiddled about for about 3 minutes and it worked.
It works the moment I get in the car now, no lead, no nothing.
Only gripe is that if I'm at the front of my house it tries to connect all the time lol.
I paid less than a tenner and have seen it cheaper since.
Car is a Nissan Leaf 2022.
