Iβm afraid I have the same issue. I have Toyota Corolla Touring Sports Premium version that comes with a JBL unit (which appears to be a Panasonic in fact). When ordering I did send the (front) picture of that unit and upon installation yesterday, none of the connectors from the original Toyota cables fit into the supplied can-bus (RZ-FT-01)connectors. And I agree, the time spent was not entirely lost, I did learn quite a lot about dismantling pannels π. I have sent a message to the WhatsApp channel of theirs and waiting for a response. My advice for new buyers would actually be to take out a stock unit first, take the pictures of the back of the unit and cables and only then place the order. Will keep you posted.
