Magnificent!

For Volume fix for audi concert1/chorus1

Absolutely great solution for a problem only a few even have. Lots of background information are provided in the github. Everything is clear, the soldered product is very well done (and really tiny) and the shipping was really fast.
Everything worked without problems, only a few steady hands are required for the installation. Lots of great ideas and refinements went into this fix, thank you very much for your dedication!

Great product

For VWCDPIC Audio Interface Adapter

I bought unsoldered version and it came with every part described by value and by component number like on silkscreen of pcb.i was amazed that it came with pins even though I bought version without connector. After assembly everything works nice without any problems.

Good job

For Breadboard adapter for F-3188 CSR8645 module

PCB is great. Power button is working but you need to be very quick. Otherwise module turn off directly. I think module needs some components or firmware change for stability.

Works perfectly!

For Volume fix for audi concert1/chorus1

This is such a brilliant device, the volume issue on my stereo has bugged me for years. I have tried fitting aftermarket stereos in my car but it is overly complicated to get everything working correctly. When I saw this I was so excited.
I was initially worried about being able to install the device but it's actually very simple and very little soldering experience is needed to do the job.
The device works perfectly and I can enjoy music in my car again without constantly battling the volume wheel! :D

Working Perfect

For VWCDPIC Audio Interface Adapter

Have an Audi Concert without AUX and without CD-changer. Purchased a Bluetooth adapter but was not able to get the radio into CDC mode. Understood that a simulation of a CDC was needed and this product worked Great! Now I can press the CD button on the radio and the radio thinks it has a CD-.changer and I can use the inputs for either an AUX input or as a bluetooth input. Hope that next version of this product will include a bluetooth device - that would be great! /Patrik from Sweden

Ottimo

For VWCDPIC Audio Interface Adapter

Perfetto, mi ha risolto un problema. Volevo collegare un adattatore bluetooth alla mia vecchia autoradio audi. Nonostante quanto promesso dal venditore, l'adattatore bluetooth non veniva riconosciuto dell'autoradio. Questo piccolo emulatore ha fatto credere alla radio di avere collegato un caricatore CD potendo poi collegare una qualsiasi fonte audio (a me serviva il bluetooth ma potrei collegare una qualsiasi sorgente audio analogica).
Grazie per avermi risolto questo problema

Doporučuji

For Volume fix for audi concert1/chorus1

Super komunikace/spolupráce. Modul po malé peripetii funguje bez problémů (bylo nutné doříznout dělicí přepážky u patice pro lepší kontakt s původním IO). Zpracování PCB skvělé, dokumentace formou "nalepení" součástek na list A4 s popisky také fajn nápad. Díky
