DIY – NAV System Conversion with working rear defrost

mlsully

You would have to make a lot of harnesses, or find a donor car for them. Plus add the GPS antenna, shark fin antenna, sat radio module, and wire up the backup cam (which is split between 3 harnesses itself). The factory nav is garbage, definitely not worth the hassle. I'm holding onto mine for when I decide to sell the car down the road.

I have an '09 Sport/Touring with the Navigation system. I liked the idea described here to convert to non-navi for custom audio installations but I am approaching it from a different angle. I am working on a way to use the base model A/C dial control module with the Navi AC amp module. This would eliminate a lot of invasive modifications to the Z to perform this conversion. For example, it would eliminate splicing into existing wire harnesses, adding pins to existing connector housings, and running new wire. It would also remove the need to source a base model AC amp (which I know isnt a huge deal, but as of now are are ~$80).

In effect, this would be a plug-n-play translator that would allow the base AC controls to operate as normal and interface with the Navi AC system. Additionally, the AC state could be communicated to an app (or custom screen) to get visual feedback. In my case, I plan on integrating a tablet in conjunction with an aftermarket stereo. The tablet could run the AC state app and provide things like Mode, Temp, Fan speed, etc, similar to what the Navi screen displayed.

Anyway, I have ordered a base model AC control module. It would be awesome if anyone had a functional base AC amp that I could barrow (or buy for cheap!?). I would pay to have it shipped both ways and would reimburse/replace it if it got damaged. I am just trying to avoid having to buy one off eBay and reselling it. I don't have a good idea of how long I would need it yet, so that may not work for most.

Trimmed your post so I'm not quoting everything but look into this if you don't mind eliminating the knobs:

Yes, I have actually implemented this project and controlled the AC with my phone. I then wrote my own application that runs on Windows to further test. It does look really neat to have everything on a screen, but I actually wanted to keep tactile controls. The two main reasons for this is that it would be way easier to implement due to being able to simply buy a base model aftermarket 2-din stereo bezel instead of the added effort to make my own full console tablet bezel (or spend way more $$$ to buy something pre-made). Second, I actually really like physical controls. I tried the whole on screen environment in the Tesla and never really liked it to be honest. Sure, I would probably get used to it eventually, buy I felt like it was a bit too distracting. At least for me. The physical controls can be manipulated without ever taking your eyes off the road and that makes me much more comfortable.
