I contacted manufacturer of our Bluetooth modules and they have no plan to update firmware so contacted Nissan head quarters and told them of 350z owners dilemma and after 2 weeks, few emails and a couple of phone calls they told me that Nissan has no plans to looking at upgrading 350z owners modules or contacting manufactures to order firm ware upgrades! so as per usual Nissan customer care and or after care is rubbish. I explained said to them, think about how many zed owners there are and we all al experiencing the same problem and even if it meant a small charge to upgrade the firmware how much money they could make if aftermarket sales! and even that did not do it! so there you go folks!
