Good product but beware of minor anomalies:

Content of the received product, but there are some anomalies that should be updated on the website:
_ The ad mentions that the reader reads cards and USB 32GB: FALSE. the maximum is 16GB (see package insert).
_ It can read up to 99CD: FALSE. it is marked in the record that the following devices, 6-10 we read CDs. For my first test, I managed to read up to 15 CDs (22 CDs: the last 7 folders are "invisible")

Small practical information:
_ I have a Citroen C3, 2010.
_ Installation made by the manufacturer (it is imperative to unlock the CD changer function trip computer + USB charge the update)
_ The sound is lower on the player, need to turn up the June-August additional notches (does not affect anything in the quality)
_ Since I do not get 99 records, I fill up every 99 Titles file to take advantage of all the allocated storage
_ It is essential to name the folders: CD01, CD02, CD03, ...
_ No need to rename your MP3 tracks (only folders are concerned)
_ The titles of the reading order is alphabetical order but in order of backup in the folder. So it is the order of copying will make the timeline title playback (marked in the record)
