I just installed a aftermarket in dash navigation running wince 7 (maybe) on my car, and the iGo 9 Primo can search and navigate accurately.

But there's a big problem, huge pop sounds, just like the sound every time you just turn on your hi-fi, occur frequently at the beginning of almost every sound iGo 9 pronounces , no matter on voice during navigation or on sound when clicking the button.

Pop sound occurs whenever I have navigation on solely or mixing with my mp3 music in my sd card. I tried turning down the volume it still does not work.

Any one has any clue about it ?
