Re: No voice to Garmin Nuvi 660
In case it is a software problem try this and see if it will fix it......follow these steps. 1. Power off the unit. 2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least). 3. Once the pre boot mode message disappears release the power button and your device will perform some activites to try recover from the problem.

Make sure the volume isn't muted. There is a separate volume adjustment for Navigation (voice) in addition to media player. Can be a bad speaker. Make sure a TTS voice is selected. More info at these links:
Haven't heard of this issue but there's a lot of surplus stuff in the memory that can be safely deleted. Try connecting to the computer so you can see the files on the nuvi. Remove a lot of unnecessary voices and text languages. If you need Turkish or whatever in the future it can always be reloaded via the free Garmin WebUpdater. If you don't have WebUpater download it anyway (from the Garmin web site) as it's an easy way to check your GPS has the latest software and bug fixes.
Plug a headset into the audio jack and see if there's audio when Jack or Jill speak. If no audio there, you've got a defective audio amplifier stage. If audio can be heard through a headset, you've got a blown speaker.
You'll need to send it back to Garmin for repair in either case, though in the case of a blown speaker, you <could> use external Ipod-type speakers, if you didn't mind the kludge.
1. Are you sure the volume setting is all the way up?
2. Are you sure the sound isn't muted?
3. Have you tried a pair of headphones in the headphone jack? If the headphones have sound, your internal speaker is bad. If you don't feel like sending it back for repair, you can purchase a FM transmitter like those used on IPODs and CD players and plug into your GPS's headphone jack and play the audio through your car's FM stereo.
4. If you don't hear sound from the headphone jack, most likely the audio output section is defective and you'll need to send it back to Garmin to be repaired.
Please let me know if I can be of further assistance to you.
Can you update the firmware on your unit
my k800i sony phone had a problem synchronising and would freeze, then one day the nuvi 660 updated the firmware by itself and has been fine since, only problem being the volume, a bit low when trying to contest with large diesel engine, onboard speaker keen to distort over 80% volume
i had the same problem with my unit. I went back to The Source and they told me it was normal. I had a garmin streetpilot before the nuvi and the sound was much better. The streetpilot has 2 speakers and the nuvi only has one. I had another problem with my nuvi and I exchanged it for another one and the volume problem is gone. Use the male voices over the womans they seem to be recorded louder. My problem is over
