yeah, i took my car to my local caddy dealer and they also said i needed a firmware update... not sure though if he meant for my denso nav or with my computer. i had asked him to recalibrate it with a tech 2 so my car knows that it has nav (it was originally a non nav) and he didn't do it cuz he said something needed a firmware update. i would like to see some more info on this too if anyone knows anything about it
