Android Auto could not be installed on Desay 187B until now.

German should be able to write through TTL, need to open the seal, open the unit. Sorry, I haven't got this file yet.

Method 1:

After the upgrade is completed, please click "Settings", select "Copyright" and then click the "media" and "phone" buttons at the same time, the project menu will appear. If it is unsuccessful, it means that your Desay 187B is an earlier version. Please use method 2.

Method 2:

After the upgrade is complete, please click "Settings", select"Copyright" , and then long time press and hold the "media" and "phone" buttons until the project menu appears, about 30-50 seconds.

If neither method 1 nor method 2 succeed, you first activate the developer mode of the system with VCDS cable. Watch this video.
