To answer all your questions
I Will copy/paste the official main information provided by RSNAV itself:
Some detailed information about the project(findings)
- It is possible to integrate 10.25" screen for C7, 7.5, D4, and 8.8" screen for B8, B8.5 clusters. The panels has to be sunlight readable.
- Original speedometer mainboard has to be kept for immobilizer and etc. It is possible to layer up the original mainboard + control board for the lcd screen.
- There are at least 3 different factory original screen panels for C7 and two monochrome screens and one color screen for B8, B8.5. In order to keep factory original dashboard screen information such as mileage current speed, current consumption, etc, it is absolutely required to decode screen signals, and overlay it over Linux based tacho interface.This is mandatory for C7, D4 with night vision since the night vision images cannot be hijacked in the middle. Furthermore, there are one challenges for each platform.
For C7, the older JDI 7" display with TX18D29VM0AAA model number, there is no longer any information about it kept even with the factory(KOE, JDI) so video signal interpretation for this has to be trial and error method. Early C7 car’s dashboard comes with this display. AUO 7" is already decoded, and facelifts uses LVDS so it won’t be hard to decode. But the JDI one would be time consuming.
For B8.5 speedometer, the magneti marelli made color screen need to be analyzed further if it can be removed or not. If it cannot be removed then the dashboard cluster has to come forward even more.
- For C7 and D4, there is only one mould so the cost of manufacturing new moulding that can hold larger LCD display is minimal. Approx 10,000$ and can be ready in 80 days.
For B8, there are 7 different shape of the speedometer and except a few B8.5, at least there has to be 5 different plastic mould tooling required so that the new cluster can be fit with the existing factory trim surrounding the speedometer. 5 different moulding would cost approx. 5~70,000$ and can be ready in 100 days.
- Hardware and UI based on Linux and QT platform would require about 100,000$ budget with 300 days to develop.
Thus approximately at least 160,000$ to 200,000$ fundraising is required.
- Installation is not simple drop in. It requires some soldering skills to remove needle motors from the original speedometer mainboards.
- Features like rear camera, front camera, hdmi input can be integrated too as well as carplay and android auto. However, to handle multiple video sources a good image processor with at least 4 digital inputs, it would require to use high end automotive video chips from Renesas, but currently Renesas chip supply is extremely unstable.
So considering this and that the time frame to develop this kind of device is about an year at least and budget goal is 200,000$. In order to keep the price under 1,000$ there has to be at least 200 reservations that cannot be refunded in the middle. assuming at least 30% of people will drop from the fundraising for whatever reason so the minimum first batch reservation has to be over 250
------
The installation is not a problem definitely, keeping the original cluster.
The biggest obstacle/challenge to face here is the quantity of preorders/barkers needed....
250 units...It is too much. We have to contribute them all the money beforehand to ensure the future production.
I think that RSNAV should believe in this Project even The crowfunding does not reach the goal proposed.
There is no Virtual cockpit for C7 Cars... And there are Many owners hoping, wishing It from long time ago.
Seals could rise up sharply as S2/ S3 screens did.
It is just my opinion
Regards
