Does anyone know what brand CAN Readers will read all computers on the G35? I have a 2003 Sedan, as well as a 2014 Q50, and I'd like to be able to read codes on both of them. The one at O'Reily Auto Parts will not read anything but the ECU. I don't want to have to take a vehicle to the dealer to read codes on the tranny, body, etc.

A good quality bluetooth reader and the proper apps on a smartphone or computer should be good.

I have an OBDLink LX dongle and can read on both my 06 G (ISO protocol) and my 08 Armada (CAN protocol).

I also have an Uprev cable that can connect to the other computers using their Cipher/Osiris program.
