Post is now premature. Local dealer did not understand the Nav VI was not the new unit.
According to my local dealer, I have just purchased the only new model Nav in Oz. I have had the Nav V since 2016 on the original Lupin, and since 2019 on the 1250 using the Vortex mount with good results generally, but with so many changes in Bluetooth over time, performance of the phone has degraded.
I am hoping that the new equipment will fix the phone dropping out.
BMW press releases are coy about its features. I will report / review ASAP.
I would like to apologize to anyone I have NOT offended. Please be patient. I will get to you shortly.
