I did a custom radio install in my 03 g35 coupe and used the Turbo2 radio kit for the 05 07 but my question/problem is that all the functions work other then the temp up and down. Is there a difference in the pinout in the plug for 03 04 to 05 07 years or is there a problem with the kit? I got the kit from a guy on Ebay and he said it was never used but I guess you never know! Any input would help thanks
