For 1st Gen Cruze owners that would like to add Android Auto or Carplay to their vehicle with minimal modifications and keep the original look of their interior without resorting to off-shore clones of questionable quality - Pioneer has released the DMH-C2550NEX. It is a digital media receiver version of the Cruze's radio & screen design and is intended for use in vehicles with limited dash installation space.
Installation is very easy. The screen is only half as deep as the original screen and about 1/8th inch shorter, so you will need to add some support for it on the screen bezel, but nothing that would be permanent and prevent you from going back to the original system later.
Optional - If you would rather use the built-in hands free microphone instead of the one provided by Pioneer, you can make an adapter cable. Directions are in the next post.
Connecting the C2550NEX to your vehicle using an iDatalink Maestro RR allows you to control the same settings that the original radio (non-mylink & mylink) controlled as well as additional functions. It also allows the headunit to work with both the standard and premium sound systems. It seems that Axxess and PAC-Audio are also starting to develop adapters that have the potential for the same level of control, but nothing has been released by either company for the Cruze yet.
You will lose use of the dash mounted radio/navigation controls, however I am looking into seeing if it can be retained with the help of the aftermarket wiring harness companies.
