Would you be interested in deleting the factory Navi? I’m fed up with the factory nav system too and really want Apple Carplay in my Z (specifically I want to run an Alpine iLX-700 Alpine-USA.com iLX-700) so I also have been doing a lot of research.

I recently down loaded the service manual for the 2009 370Z and have figured out how to delete the factory nav. It’s all theory at this point because I'm out of country and cannot test it on my Z. Every one says it can't be done but I think they are wrong. It is definitely not a plug and play mod. It will require a custom made wire harness, adding pins to a connector, building a connector, buying the non-nav A/C vent controls (eBay) and a complete deletion of the whole stereo system except the wiring harness. This means you would have to do a complete aftermarket stereo install, wires, power, head unit, speakers, everything. If you are worried about making permanent changes, my plan will retain the ability to put the stock system back in. If you are interested I can do a write up and send it to you. Let me know.
