Back again!

Having fixed some serious problems with the sam(drying it out) I am now concentrating on the radio. The unit is a belsee unit which is like most of the generic Chinese android units. It has CarPlay and looks like it fits the carw203.
If I plug the unit in, it works fine and I can drive the car. However, it causes the high beam to flash every few seconds and the indicators do a ‘double click’ every so often. Unplug the radio and the gremlins go away. It does not seem like a power drain issue and I suspect a canbus problem but I do not know how to fix it. Any ideas?
