It runs Google Map so I'm sold already. Can't the Rebel system be upgraded to 8.4?

Im thinking lots of the Canadian models have the 5.0. After I bought mine(5.0 version) I looked around and noticed the majority of Rebels I found around here have the 5.0. I like my 5.0 with the alpine system better then my 8.4 I had in my '14 Sport....if I had the Nav in my '14, it would probably be a different story though. With all that being said, I would love to upgrade to that Alpine x009-ram but the price is ridiculous! So I'm still hoping some comes around that's in a better price range.My Rebel is 8.4 already. Without the 8.4N (Nav). I think most Rebels are. I've only heard about a couple that were 5.0.
I think that it is possible. Possible enough to enquire at your dealer.I wonder if the software upgrade can be done on my 2015 8.4n
