Cool steering wheel with turn signals and sound effects

Since the original steering wheel of our Bobby Cars two "flaws" had (first, the hole for the retaining screw was inclined, you held the steering wheel straight were the wheels slightly to one side, the wheels were straight, you had to grab the steering wheel wrong and secondly, the horn was so stiff that my 12 months old daughter could not operate) I am on the search for a replacement made and finally got stuck in this fine specimen.
Here the installation is straight and all the keys are sufficiently smooth. In addition, there are different sounds (horn, radio = Bobby-Car-song, starters, telephone, central) and lighting effects (turn signals and hazard lights) that make the new steering wheel entertaining for a child.

However, I have Mrs. L. (see review by 16.8.2012) rather give that part is pretty loud. As I held the steering wheel during the test at arm's length, the volume dropped me not adversely affect, but have children much shorter arms and therefore are much closer to the speaker that sits in the middle between the speedometer and tachometer.
Remedied by a small strip of adhesive tape, which, glued over the three slots of the speaker, reduces the noise level on the living room and at any time be removed again if necessary (outdoor use, bigger kids, etc.).
