I had aawireless a while ago and it was perfect, you'll get an app on your phone for firmware updates and some advanced settings. I have Motorola now and it's bad, it overheats on long rides and starts disconnecting, no firmware updates, it's not worth it. Car is Mazda 3 2017, phone is Samsung Galaxy Note 20 Ultra 5G
Last I checked aawireless was out of stock worldwide except in Amazon US
