The garmin nuvi 660 (has truck routes)the speaker doesn't come in clear sound fading. What can be done to fix it? thank you from: truck drive in need. I purchase this garmin A few months ago. I understand this service is fee to ask questions

Most likely a defective speaker. Try using headphones. if the sound is good there, then the speaker is bad and needs replaced. More info on this topic can be found here:

First - look at your Route Options and see if you have any avoidances set and whether they are really what you want. Check you other route option settings while you are there to be sure it hasn't been set to some mode you didn't intend (like pedestrian).

You will likely find that your problem is in your route options setting, but if it isn't, then log on to http://www.garmin.com, select the support button on top, and then select contact support. There is both a phone and an email option. Garmin offers free technical support for their units.

Sounds like your speaker went south. Since your fm transmitter is working I'll be your earphone jack is too. So you could always use an earphone. Only other option is a speaker replacement.

If you can hear audio through the headphone jack but not the internal speaker jack, then the speaker is bad.

This is a problem I have seen many times before. I will be posting an article soon on how to replace the internal speaker, however this is not a repair that just anyone can do.

You have to have skills in dissassembly & soldering.

Because this GPS was manufactured really bad is why that happens.
Before its too late I'd get a refund right NOW!
You are 1 of 5 other 660 GPS problems.
The only GPS problems are the same 660s

Hope this helps - Josh

Make sure you don't have the sound muted. Have you tried plugging in a set of headphones into the headphone jack? If you can hear sound with the headphones, most likely, the internal speakers have failed. If you still can't hear any sound, the audio output stage on the motherboard has failed. In either case, you will need to send the unit back for repair. Be sure to have your serial number handy. Register it online https://my.garmin.com/mygarmin/marketing/register.htm

i have been told that voice to street is not as clear as the voice just stating turns. If it really bothers you then try voice to turn. I cant remember the setting but it should work well for you.
