Query: Useless

1st Received - Had a button broken. Did work but right arrow would not click.2nd (Replacement) - Did not transmit the bass. I almost bought a new stereo system for my car thinking my speakers were bad, but tested the product in 5 other cars and had the same problems.I do not recommend this product.Me and all my family have the previous version, with manual setting. That one is excellent and I will probably buy me one more of those.
