Sorry to hear about your nav problems. Your brain unit in the trunk is going bad. It seems to be a common problem. I myself went through this last year. First it was intermittent and then it jus completely stopped and I lost control over nav, air, audio and everything else on the center console. The dealer charges around 5700 to replace the unit. I have an extra brain unit from my wrecked m45 and if you want it I will sell it to you. let me know.
