If you still have your Rodeo, maybe you can check the pinout fron the Vehicle itself.
As for myself I'm going the BMW way. It fits the Single Din for the changer. Those without the changer should be happy. I heard they even have a digital version.

I asked the seller :
"Hi,what colour is the illumination and does it come with the pigtail?"

Hi there the illumination is an amber colour and the connector going to the clock is a 3-pin female thanks !
