Hello everyone!
Big thanks to all the OGs who wrote all the instructions - thanks to your contributions I was able to update the software from the SMEG5.0.D.R2 on my Peugeot 308 II T9 to the latest SMEG5.43.A.R2. Guides were really good and results amazing - sound quality actually improved a lot!
Relevant for this thread is that internet sharing via Bluetooth doesn't work with newer phones unless you update your SMEG+. Before updating it was always greyed out for me and I could not get internet sharing to work at all. After the update, I deleted my connection profile and connected again - and Internet sharing started working!
Next I am planing to use this guide to calibrate the SMEG+ into feeding low-level audio output to the speaker wires. The line-out output should make connecting an external amplifier (which I am doing) much easier and much less noisy and distorted. It is allegedly possible to calibrate this, but I couldn't find any evidence/mention online of someone actually doing it. Maybe someone here had tried it, or knows if it is actually possible?
In the SMEG+ documentation, there are clear indications that it is somehow possible to get line-out from the head unit:
and further specifying that only 2 instead of 4 outputs shall be provided in the HIFI CAN mode, and that they apper at the front speaker terminals:
I would assume the way to trigger this HIFI/CAN mode is to calibrate the following parameters: Arkamys_parameters to 2 and Audio_Config to 2. I think the "Arkamys Function" from Arkamys_parameters is actually just an equalizer profile applied to audio signals so the factory speakers sound better, and that it can be deactivated to get the unmodified audio. Assumption comes from Arkamys mode being active by default in my cheapest SMEG+ (no navigation).
If anyone had done this before, I'd very much like to hear about your experiences! If not, I shall try it in a couple of weeks and report back with the results
