Design well; Functionality deficient

The signal is superimposed by a strong noise. While the built-in MP3 player works, unfortunately, not user-friendly navigation. However, it can playback to select a track number is not always what is started. After each track is done in my model no automatic switch over to next. The quality of the FM stereo signal acts in the frequency range and severely curtailed and the signal / noise ratio is insufficient for music enjoyment. The remote control is visually not reliable so that a high frustration tolerance is required by the operator.
The addition "for iPod suitable" can be applied to any transmitter with a jack input, and thus irrelevant.
A switch to deactivate the device does not exist. Thus it can be taken 100 from the electrical system only by staking the FMT.

Auser optics I can no recommendation.
The main task should be a good signal transmission, implemented insufficiently in my model.
