“The Bluetooth module is installed in an aluminium toolbox. I have a fridge in there with Bluetooth also. From the drivers seat I can control my fridge via Bluetooth but the kickass Bluetooth module (which is mounted closer to the cab inside the toolbox) and I can’t connect to it from the drivers seat. I understand the faraday cage but if one Bluetooth device works and one doesn’t I can only assume the signal is weak. Have tried emailing kickass but had no reply. Am waiting for a phone call hopefully. All the other gear I am very happy with.”
