eZ Navi Delete Interest/Availability

I'm interested. Any idea if this would work for all year/navi models?

Count me in and thanks for all of the time and work that you've put into this project. You have made a tremendous contribution to the community.

With the recent mod I made to the board, it should be compatible with all years with the addition of the universal connector! The top connector on the board used to be the 40 pin connector that is present in the 2009 model year with Navi as that is what I have. I replaced it with a generic 20-pin connector that has a universal pinout so that a simple wiring harness adapter can be used to adapt the board to any year (and this connector is cheaper so the added cost for the adapter breaks even!). I have the Universal Wiring Harness Adapter definitions up in the Wiki on the Github site.

I am considering not populating the Bluetooth module.

The reason it was on there was to provide a wireless connection to Android Tablet based setups so that the USB port could be used to charge the device. Since then, I see that Braniac has come up with a charging USB hub solution (Mk1.5 Electronics) that allows their system to charge and use USB OTG devices at the same time. This sorta defeats the purpose I had to add Bluetooth... There is no firmware developed for this function yet and it would make the boards cheaper to non populate it. I would leave the footprint on the board so that it could be added later if desired, but I think the majority of people interested in using this feature would just use the USB interface to the device.

Thoughts?

The weakness that I have found with the OTG cables enabling simultaneous charging and data transfer on my Android tablet is finding quality cables to support charging, and especially when needing an left or right angled cable to fit the space constraints. I probably tried 6-8, most of which were trash.

So, my preference would be to pay for the bluetooth connection.

From what I understand though, Apple uses some proprietary stack which might make developing the firmware problematic for Apple devices, though I don't think it would for Android. This may be out-dated info; but something you would want to check if not already knowledgeable.

Yeah, I suspect that people going the Brainiac route would just rely on the product that they were purchasing being up to snuff. I have looked into the OTG/Charging solutions and was not very impressed. The problem is that OTG is a broken standard, so it doesn't all work the way you expect it to with all hardware that states it "supports" it.

So, I decided that I would leave everything in place except the Bluetooth module. It would make the boards up to $10 cheaper to leave off and can be added on as an extra for those that want to use it.

The last time I messed with Bluetooth modules was back when the SPP protocol was standard and you could communicate with other BT devices as if you were talking to a serial port. Now with the newer BLE devices, protocols like SPP are not longer standard and you have to make your own. Ugh...

you're getting me excited
