I'd like to know about the radio as well. My radio has been acting up and the manufacturer has new firmware but to install it you have to put in a sd card on top of the radio. The front panel is enbeded in the dash so you can't get to it.
Just took my Axerra head unit out and the front trim is just snapped in. I used my fingers to pull it off. Then you need the special tool (two small long metal strips that were in the owners manual bag) to pull the unit out unless you can access the unit from above (remove the top of dash).
