GR Yaris Retrofit Yaris Cross Headunit - it can be done!

Hi folks, looking at doing this swap myself, been reading up on it.

The one open question seems to be the DCM, and therefor SOS / MyT functionality. Not a deal-breaker for me, but be nice to get everything working.

So the factory DCM (86740-0D031) won't connect to the new Smart Connect head unit is that correct? As the Smart Connect has the flat 5-pin connector which the old DCM doesn't? But all of the old DCM's cables do have sockets in the new Smart Connect, so has someone tried this?

Or what about leaving the Smart Connect's DCM (86740-YP010) connected? Anyone tried that? Does that work if you just enroll it into the MyT app as a new car?
Drop me a PM bud. I have the newer DCM on mine and will try it out at some point!
 
Has anyone got any tips on how to actually do this swap? I had a look and can't work out how to get the bottom part of the plastic surround off to get the unit out, and then it looks like it's held in with allen bolts with epoxy over them? Is this a no-tools job or more difficult?
