mine is skyline 350gt type SP which equal to g35 with premium package.however as the it an early model, my Bose system doesn't have the driver audio stage function. would like to know if anyone know if below amp serial have the driver audio stage function. 
1) 28061 JK000
2) 28061-JL02A
i read that some guy manage to add this function by changing the Bose amp to the newer model. from 28060-JK61A to 28061-JK61A. he bought the amp from dealer which cost him almost 1k. im looking for something from ebay, and infiniti dealer wouldn't help me by email, and ask me to go to nearest dealer. fyi im in japan.
thanks for the help.
