The 2014 Pioneer NEX series of radios is compatible with Maestro to retain Sync. However, Pioneer did not include the extra screens (Climate, Parking Assist, Gauges, or Vehicle Info) in this year's models. So, unfortunately, that means you can use these radios with a Maestro RR and FO1 T-harness, you cannot use them with the MUS1 dash kit as you need a climate screen in the radio.

Also, these models are already shipping, but will require a software update to be compatible with Maestro. We have been told that will be available in May/June time frame.

Best,
