This box works with the Citroen C4 Jbl package. Radio RD3.
However, not entirely without hesitation ...
The red wire must be contrary to the instructions associated with the permanent power cable of the radio. Between then heard a switch soldered, otherwise the battery after a few days life is empty
The sound is supi
SD card and USB stick are well recognized (FAT only). However, the RD3 can not display title list. Also, only one input can each be loaded, otherwise nothing will be recognized.
But what does not matter, as I have already hanging by a jack androids turn.
The Bluetooth function is doing as it should.
Recommended,
RD3 drilled with Navi, mp3player, Video Player, Torque Info key, etc.
