I'm working on installing 2 dashcams, but might opt for a larger DVR solution if it's easy to grab a copy of the around view camera video.
All the cameras are connected to a separate module that combines and "stitches" the four images together. That combines signal is then sent to the A/V control unit up front.
Thanks, somehow I missed this response. In hindsight, I guess I would have to worry about powering these cameras as well, so I'll have to give it some more thought, but being able to record all 4 cams with 1 video input would be really useful for sure.

Why not dump the stock unit all togheter? and then reverse engineer the climate data off the can-bus?
Is the main concern that the carwings will stop working?

I'm hoping something comes of this thread! Could this be helpful:

It tricks the car into thinking it is in park, enabling the rear video camera to work. In other Nissan vehicles, it allows you to watch DVD's.

Might there by any way to create an RCA audio-out bypassing the built-in amplifier?

I don't believe so, but how long are you there for? We're moving to the U.S. in a year... We want to take our European LEAF.

I feel an MFD swap coming on...

In all honesty, you may be better off finding a scrap LEAF and pulling the MFD out of that?

Obviously this was accomplished without altering any code, but a more elegant way would be to patch the code to eliminate this (any several other) annoyances.

I would like to ask you 3 questions Phil:

1. Did you test this hack with a phone, which is connecting via the Bluetooth, because while the Bluetooth info-message is displayed, the user cannot press the "OK" button:

2. How much soldering is required to install your "hacking" microntroller? I mean, do the user have to solder simultaneously more than 2 pins?

3. What will be the estimated price of your hack? I would like to buy one, if the stupid lawyer from Nissan cannot be persuaded to drop this retarded confirmation screen in the following 6 to 12 months. (I love the LEAF, but this nag screen is like a "Spoonful of poop in the barrel of honey".)

Best regards.

I'm hoping we can sneak CarPlay onto this thing when it becomes available.

I've made a small screen touch simulator based on µC - you need to solder 4 small wires to touch screen sensing plate connector - so no big deal

Could you please share some more info?
Like, what protocol are you using? 5V or 3.3V ? Are there wires for power available, or do we need to get that from somewhere else?
Maybe you'd be willing to share some source?
Any piece of info would be nice!
