I had a bunch of TSBs done to my car recently, as my warranty is almost done. I had the dealer do a few to the head unit as the ambient lighting and audio would act weird at times. Interesting enough when they applied the TSBs Siri Eyes Free is now enabled on my SHO. Up until now I had to hold the home button on my Iphone and the display would be unknown caller. Now it says Siri and I can access Siri by holding down the voice button on the steering wheel. My sync software was up to date before they applied the TSBs. So whatever they did it is now enabled and working. Just thought I would throw it out there in case anyone was wanted this enabled on theirs. I have listed the TSBs that I pointed out to my service tech, I am not sure if they were all applied but getting this to work is welcome.
