Memory card read error

I use this memory card for audio MP3s to then play in the car on a VW RCD510.
Everything works fine, if it was not always this sudden memory card read error, which silenced the music and the play off. Have the card again reformatted and rewritten, have the impression that it is getting better after that, nevertheless continues memory card reader errors. I've tried yet any other memory card, this trial is still pending. Since I assume that these problems associated with this memory card, only 3 stars.

Addendum 03.03.2015:
The formatting brought absolutely nothing. Now I have for quite some time a different memory card in use and lo and behold, the memory card reader errors belong to the past, I had never since.
Because these read errors are now safely on the memory card from Transcend, I draw from my original review from 1 star, therefore only 2 stars. Actually, yes a map constantly read error ever produced nothing of value. Good that it was for me only to MP3s, which I have always available elsewhere.

My new memory card with which I am completely satisfied this is here:
SanDisk SDSDXN-016G-G46 UHS Speed ​​Class 3 SDHC 16GB Memory Card

(There are 4GB)
