BMW's position seems to be that it is not willing to assist in this upgrade. I agree with you that the 4G telematics module could be installed. There probably would be some configuration changes that BMW would need to make to associate the new 4G cell phone number with one's i3, but this doesn't seem impossible as BMW implies. Very disappointing
Doubly strange is that they are offering the upgrade to other BMW models of similar year manufacturer. An owner posted on FB that he got two letters from BMW one for his 2116 435 and it says the upgrade is available, and got one for his i3 that says it is not.BMW's position seems to be that it is not willing to assist in this upgrade.
Me, also, for our 2014 i3. I just don't believe that no 4G upgrade exists.
According to the BMW Dealer parts lists - it exists. A check of the 'what it fits' list shows that this is a universal part, which fits all BMWs including all years of the BMW i3. BMW claiming that an upgrade 'isn't available' for the i3 must mean that they made a policy decision not to support a car model that they plan on discontinuing in the near future.Me, also, for our 2014 i3.
