First the sound is really mediocre and désageéable, little power but mostly no relief (no bass and treble: everything is Merme level). I was not too demanding given the low price but this is really more than disappointing. Also the wiring is reversed compared to most vehicles so that the post does not keep in memory the stations. It would reverse two son on the existing wiring of the car. Given the mediocrity of the apparatus I have not seen fit to do so. I preferred to return the radio to me reimbursed by carefree AMAZON (thank you). I can not recommend this product.
