Although hacking but for proper operation!

First thing: walk 2.5 seconds and the auto reverse car radio "spins" the playhead; So 2.5 seconds (approximately) of silence. Re-reverse and go again for 2.5 seconds of music ... Can not hear music normally.
THIS IS WHY a little manipulation to con is to do for those who have the same problem as me:

-Put The adapter into the radio and read music. During the 2.5 seconds that the music happens, remove the adapter from the car radio;
-Remove The adapter screws and open it;
-Remove The wheels in the 2 holes on the adapter features, and even the other wheels, which are responsible for triggering the auto reverse. 1 or 2 will remain in place; do not force it they are fixed.
-Once Done, gently tighten the 2 parts of the adapter, always taking care not to damage the cable or the pickup.

Voila now you should be able to play your music continuously! As a precaution keep the wheels in order to replace them in case the adapter pickup was not on the good side.

Well if the audio quality is correct, do not expect a home cinema quality, but its possible to recycle our old radio !!! Be careful if you need to do the manipulation 'described by the extreme fragility of apparent son attached to the adapter's read head !!! Good for 6.00 euros not expect to shield Kevlar good but watch out as well !!
