Just wondering if anybody has installed a Ebay head unit Radio/Nav/Bluetooth etc.?

I purchased one made in China and came from China even though he listed AU stock Regents Park.

It actually works quite good for a minimal amount of money, did take some stress to get going no instructions and seller obviously did not know much about product he was selling going now and happy except for one problem seems to be Can Bus related, has a car info screen which shows when you open door etc.

Not no problem sitting still but when you put on seat belt and drive screen fluctuates between entertainment and car info like struggling with the seat belt anybody had this problem?
