Review on BTBcoin Diagnostic Connector Transfer Mercedes by John Invert

I bought a new Innova 5410 to check various vehicles. The scanner worked on a 2001 Suburban, 2001 Chevy S-10 but WILL NOT work on my 1999 Mercedes CLK-320 with this adapter cable. The Innova scanner is compatible with Mercedes and can read data in European Mercedes format. The cable adapter is correctly indexed with two guide slots and fits perfectly. The adapter turned on the scanner, but was unable to connect and transfer data. I tried several times to transfer the data. I've unplugged/plugged it in several times to no avail. I made sure the ignition key was ON and even started the car to get data while the engine was running. I wanted the adapter to work but it just didn't work. :( They return.
