Will find out tonight during the announcement, but the new Mazda 3 should be getting a new software upgradable head unit. Not sure what nav maps it will use. If the 3 gets a new unit then most likely, the 2015 CX-5 will get it as well. Given how much I dislike the audio and navigation controls, I think I will consider an upgrade in 2015. The CX-5 should still get a dedicated sub, LED foot well lights, and a few other things. Throw in the diesel, and I might not feel bad trading in a car so quickly.
Wonder if they do release a new unit, and the dashboard remains the same, might it be possible to get the unit OEM and add it in to a 2014. Can that be done with the 14 unit to a 13 CX-5. Actually my assumption is that they are the same between 13 and 14, just the firmware load is a bit different.
