I took my car in for service yesterday 'cause BMW assist couldn't get the location of my car. I just got a call from the service and said they will be updating software for the nav. and I mentioned about the RTTI not working afterwards. He told me not to worry 'cause there's a on/off function in Idrive? He also told me the car would be ready tomorrow so I'll check and let you guys know. I hope it'll be ready tomorrow, got X3 as a loaner and I really miss my X5.
