This is a Blaupunkt CDC-A08 emulator. It reads MP3 files from SD card and send the sound to HU. HU thinks it's talking to normal CD changer.



Here is one of the first tests:

Since the video I made a lot of progress on the software. It still needs a bit of polishing before the unit is ready for testing in my Audi A4.

After I finish with Blaupunkt protocol I plan to go after the factory VAG Head Units. Maybe Sony and Pioneer after that. It depends when I can find cheap parts on eBay for testing.

This is a 4 7-seg display that can be used to measure boost pressure for turbo cars. It has multiple display modes that tyou can set. It uses MPXH6400 pressure sensor that measures absolute pressure up to 4Bar. So you can measure up to 3 Bar of boost pressure. We tried to keep it as compact as possible. It measures only 31x16 mm. It has four 2mm holes that should make mounting an ease.
