Steering Wheel Remote Control Solution (SWRC)

Early production units of the CDE-W235BT may not work properly with some steering wheel remote interfaces.

The tolerance for the SWRC port was improved which leads to a situation that certain Steering Wheel Remote Control Interfaces won't work as expected.

Bluetooth Firmware Update

The Bluetooth firmware update software has changed.
This means that this Software Update must be applied before the next Bluetooth firmware can be carried out.

Cyrillic Phonebook Support

To correct and implement these issues, there can be a software update applied.
Units which have the letter 'A' applied to the serial number are already fixed from factory side.

Please note, that this software is only compatible with the CDE-W235BT! Installation on other models will cause unrecoverable errors.
Make sure, that the software update is applied properly, you do it at your own risk!
