anybody with a GREDDy turbo timer ? how do you turn off sound
 

i try following the manual in where you can turn off the sound when powering up, count down but doesn't seem to work so i keep hittng the select button

Here's how to change the opening music...
 

With the car running, press and hold the power button for about 2 seconds until it displays "Snd" and then "oFF". If you want to go back to the factory programmed startup music, repeat until it says "Snd" and then "OP.1". I haven't been able to turn off the short tune it plays when it starts to count down but then again, I haven't really tried playing around with it either.

I hate beeping so I ripped the piezo speaker out of my Blitz...
 

that did it!
