Got 2018 model with columbus infotainment. 

 

Is upgrade possible? 

Why would you even consider this?

 

I may be wrong but from what I've read, MIB2.5 is far better than MIB3 which is designed to monetize you. And it is a pile of shyte with bugs galore that don't appear fixable or are unlikely to be fixed. Not sure but doesn't MIB3 have control functions not present on MIB2, climate controls for instance, so I expect lots of control module and wiring changes.

And MIB3 is locked down with new security protocols far more than MIB2, so certain modding will no longer be possible.

No longer to update maps easily or for free, your choice.....

 

Others may tell me I'm wrong, so lets hear....

No

 It falls into the category of not much reward for a lot of effort.
