As I already mentioned and as Zibert already discovered, the tuner modules are different between the US and EU Mazdas. Note that Zibert already successfully put the EU firmware on the US CMU and everything worked correctly _except_ the FM radio.
He actually needs a different tuner since FM is different between US and EU. In the US the channels are 200kHz wide on odd frequencies and in the EU they are 100kHz wide.
Assuming that I get my hand on an EU tuner and disassemble it in the following weeks, I'm pretty sure that I can give guidelines for converting it from US FM frequencies to EU frequencies by flashing its firmware. We need to dump it from one tuner and flash it to another.
Hi!It's a tuner unit firmware issue. The RS485 tuner addressing is done in using channel units instead of absolute frequencies. As such, any US channel number would be the double frequency in Europe. We don't have any dumped firmware images for it so there's no chance you can convert it on your own. If anyone is willing to donate a US TAU and an EU TAU, I can try to dump their firmware.
Since this is a difficult operation, I wouldn't recommend it and would recommend just buying a TAU from an European Ebay seller.
I am working on this right now. I've asked a kid that has some spare time to fill the Tuner model DB with their features from the European gEPC and I'm going to pop the cover on my first tuner in the following days to read the firmware.Hi!
Is there a question to describe the procedure for removing the TAU firmware dump?
