I am spoiled from previous "cheaper" Car Hifi´s:
in germany I was able to read the artist and title in the radio display during listening to the radio (it mostly worked for the south of germany...)
The RNS510 must have had a previous Firmware version with enabled radio text (as far as I remember FW3750).
As I tried the 2720_fix CD to activate the hidden menue and the VIM, I thought that it might also be possible to reactivate the radio text inside the Firmware.
With "Notepad++" , I tried to search the words "radio text" and found them in the file:
the comand was called "eto_rec_RadioText_Lost" .
Does anybody konw, how the reactivate this comand???
