I have been following up contact with this manufacturing company in Shenzhen, China. According to them the unit for E46 is ready for order now.
I buy a unit for Mazda3 in May 2010, so far it works and the build is in good quality.
Better to visit Shenzhen to do purchase (So you can check on the unit personally) instead of order online. You may not know the quality of the finished product now. No one do review on this product online so far.
Wah u go there for Audio or something else oso hehehe:rolleyes:
