The Ultimate Bluetooth solution for your car

An I-Bus enabled, fully integrated Bluetooth module for your BMW, Land Rover, or Mini.


Due to the current state of the electronic component supply chain, the BlueBus is unable to be manufactured. A more readily available Bluetooth module is going to be used in the next hardware iteration of the device so that it can hopefully be available for sale in mid-2022 again.

NOTE: The above does not apply for orders placed for hand built units with an original ETA of late December. Those should ship by 2022-01-31.
