Hello Tony, hello Mark,

thanks for your quick replies.

@Mark: Modern soundcards have sample rates up to 192 kHz

Anyway i have decided now to install the empeg too after i have replaced its VFD display.
After that the empeg controls the tuner as designed and the sound of the car pc can be heard across the aux input of the empeg.
The car pc could be used to do navigation and video only.
In that case i have to read the RDS/TMC stream in real time with the PC from the empegs serial or USB interface.

@Tony: Is this possible and is there a list of the available serial commands?

Further i could use the car pc to easily put new songs, which i have copied to it via WLAN, on the empeg (btw. is this possible at all if the empeg is in its sled?)

Thanks and best regards,
Andres
