Installation location 

The aerial tuner is on the M-ASK motherboard under the drive for CD, CD-ROM or DVD.

Construction 

The aerial tuner consists of a board with the single-tuner radio. In conjunction with option 663 or option 606 this board also contains the two-tuner radio. Both aerial tuners are provided with a heat protection shield to protect them from irradiation. Both tuners (not Japan version) can be coded for the whole frequency range.
