Increasing volume

Hi OldToker,

If you're using the "internal speaker" there's not much you can do other than by turning up the volume, of the "Audio Output", on your 660.

Using the built-in FM Transmitter will work, but trying to find an FM station that will give you great results, is a hit-and-miss proposition, at best.

There are 2 non-technical ways to accomplish what you're asking, and they're both not only inexpensive, but they also improve the volume 1000%, without the interference you can experience, using the "wireless" FM Transmitter.

#1. If your car has a cassette player, buy a cassette adapter (usually under $20) and plug it into the headphone jack on your 660 and insert the adapter in to your cassette player. Then make sure the audio source on your 660, is set to "Internal Speaker".

#2. If your car doesn't have a cassette player, but has an audio jack on your car stereo, buy a 3.5mm stereo audio cable (with a male connector on each end - usually under $15) and plug one end into your 660's headphone jack and the other end into the audio jack on your car stereo. Then just make sure the audio source on your 660, is set to "Internal Speaker".

This improves not only the volume of the Garmin voices, but also the volume on your alerts, .mp3 music files as well as the volume on your Bluetooth phone connection and you won't experience the "fade-in-fade-out" you get using the "wireless" FM Transmitter, built-in to the 660. A winner all the way around...

One final tip: Check the audio volume "output" on your 660, because at whatever level it's set, it will affect the "available volume" you get through your car's stereo. I leave mine set at 100%.

HTH (hope that helps)

It seems to adjust voice volume besides being fun

I agree with Sundry, just be careful you don't turn it up to loud or the units will begin to clip. Although volume problems are the nature of the Nuvi.
