Questions & Answers

Q4 : How do I connect to wireless Carplay using another iPhone ?

A:

For the multiple iPhones connection, the U2C–Air can remember multiple iPhones which have connected but only will connect the last mobile

automatically for wireless Carplay.

When you need to use a 2nd iPhone for connection, it needs to turn off the last mobile’s Bluetooth & Wi–Fi function(or not in the car), and then press

the ‘smartBox–XXXX‘ Bluetooth device again in your 2nd iPhone Bluetooth

setting.

It usually takes 5-15 seconds for the 2nd time connection entering to the

wireless CarPlay interface.

Q5 : Why Carplay stays connected after getting out of the car?

A:

For some models encountering this issue, it is due to when vehicle engine is turned off, the power supply will remain powered for a short time from the car’s USB data port, the adapter is not set to turn off automatically.

So wirless Apple carplay will continue to run for a while then turn off. You can turn off Wi–Fi manually to disconnect wireless Carplay immediately.
