Speaker works for playing of MP3 songs but does not give direction instructions when on purely satnav. Have tried increasing/decreasing volume but no sound comes out of the unit. Have also done a factory restore but this has not worked either.Speaker is not muted....any ideas?

mode: for repeat
10+Album: to change song more than 10 like 11 19
Skip/Search: press one time will go to next song press and hold search the song
Play/Pause: start playing song or make it stop
Stop : stop the song you are playing
Eq/Prog : setting menu
Vol+- increase or decrease the sound

First press the speaker symbol and check that the volume is not down fully or that the mute box is not ticked. If it is press the mute box to untick it or increase the volume. Otherwise follow the instructions below.

1. Press Tools, then press Settings (or Locale on some models), then press Language. You will see a bar for Voice. Press Voice and select a different voice. If this doesn't solve the problem it's most likely because the voice file has become corrupted. To replace the corrupted file.
2. Download webupdater from http://www8.garmin.com/support/collection.jsp?product=999-99999-27 and connect your satnav to your computer. Install webupdater and your satnav will look for updates. After it's finished it will give you an option to download voices. Click the ones you want and press next. The voices selected will be downloaded to your satnav.
When you have removed the satnav from the computer you'll need to select a voice again as described in para 1 above

yes i have the same problem, only the alarm noises work. And when i take my headphones out, the noise level beam goes away.:S who can help me ??

press the vol button then press next song button to increase volume and the previous song button to decrease volume. Then, press vol again to exit volume setting mode.

okay if you notice, the headphone switch should have a + for increasing volume and a "-" for decreasing volume, in the middle is this groove part, which can be clicked aswell. Click the middle to play/pause. And double click it twice really fast to skip to the next song! Enjoy

If it wont let you turn it up its a simple problem its the connection inside take it back its the only way unless u can take the mp3 apart and reconnect it

pretty simple.
BUTTONS:
>|| : Play/pause. press to play/pause. press and hold to power on

+ : Plus. press to go to next song, press and hold to increase volume

- : Minus. press to go to prev song. press and hold to decrese volume

LOCK switch: locks buttons, prevents loading/erasing songs

SHUFF/NORMAL switch: switches between normal and random playback

that's about it
