Question about Garmin Nuvi 660 GPS Receiver

1 Answer

The earplug/headset input on my Garmin Nuvi 660 is broken.

The connection for the earplug input is broken. If you wiggle it around you can sometimes get sound to come through the earphones or "outloug" so that everyone can hear it. This only happens when the earphone connector is about halfway into the Garmin.

When you try to adjust the sound it says that you can't because you have the headset plugged in. The headset is not plugged in. I would love to find an easy fix for this because Garmin wants $250 to fix the problem, regardless of what it is. I can buy a new Garmin Nuvi 660 for the same price.

Interesting problem but I have repaired this problem before. This is not going to be something you can fix yourself.....believe me... I have 30 years of experience in Electronics.

The headphone jack either has to be resoldered or replaced. When its loose, in most cases the pins of the jack are broken and/or the printed circuit board tracks have been torn off the board. The jack is a surface mount part.

A new jack must be installed but there is no way to solder in a new jack because the printed circuit board tracks are gone. The new jack must be installed with epoxy to the board and new wires have to be soldered from the printed circuit board to the jack.

There's around 2 hrs worth of work involved in this repair.

My garmin 660 won't transmit audio through speakers or fm transmit. I go to audio output and it says that "Audio output can not be changed when using headphones" I can use it with headphones...


You have a problem with the headphone jack. Please see this link and read the section about BROKEN HEADPHONE JACK

http://www.sharc.net/gps_audio_repair.htm

Because there is a broken connection, your Nuvi thinks there are headphones connected at all times, so you wont be allowed to change the sound options. I've repaired this problem many times. Don't try it yourself, you risk damaging your Nuvi beyond repair.

Thank you for your question.

Go to the Garmon.com website. Check for an "update for your Garmin Nuvi 660 GPS Receiver. Download the update which may take a while. It's best to start downloading and go do something else for a while until the download is complete.

If this doesn't work, contact support at Garmin.

Go to the Garmin website now (click here)


If your unit was around $100 or so, it's easier to just buy a new one then to send yours in for service.

I found a discounted unit online:

Discounted Garmin GPS


Hope this helps you solve your GPS problem.

Garmin 660 na repair


Please do not try to repair this problem yourself. You risk damaging the case and/or LCD display. In many cases, the headphone jack connections must be reinforced with wire and the jack itself needs to be epoxied to the board.

Internal Speaker Dead!


If you are using the the "audio out/headset" jack say with a cable to your aux in on your stereo then you have to plug an external mic into the base of the unit where your Nuvi is connected. It's the next size down from the "mini" plug and is located on the left site (Nuvi 760). In other words...external audio out then external mic in.

The nuvi mic works with the audio out unplugged....

THANKS GARMIN!!!!!

Garmin Nuvi 660 shutting off


It sounds like your battery is defective. They can be replaced. The Motorola phone cable is not wired exactly like the Garmin, and your Nuvi thinks it's connected to a PC. Radio Shack carries a charger for the Nuvi. I have one myself.

Let me know if you need additional help with your battery problem.

Speaker of garmin nuvi 660 doesn't work anymore


Bruce,

I measured a speaker on a Nuvi that I had opened up on my repair bench. It measured 7.8 ohm. I'm pretty confident that your speaker is bad.
