Ä° tired to remove "ding" voice hearing before every navigation voice. i found this voice in the audio folder in data.zip folder. The name of it"!ding.wav". i replace this folder with the "silence.wav" and rename the slince.eav as !ding.wav.

The result is Failure. "System startup in progress. please wait" message is freeze on the screen of f500 permenantly.

Wha tis the problem as your opinion?

i think i cant zip the alterede data file correctly.

How will i zip tha DATA file correctly?

No you do not unzip the file you just transfer the whole .zip file to the unit so leave the file as .zip and transfer it like that okay.
