Question about Garmin Nuvi 660 GPS Receiver

1 Answer

Caller gets echo of own voice wnen using bluetooth

I'm a new 660 owner and very impressed except with bluetooth functionality. The caller gets high level of his/her own voice during a call. I've done tests: Echo is much worse if I route the Garmin audio output to my car speakers via the 660's FM transmitter. The echo stays with the caller even if I turn the car radio off (i.e. the echo is not caused by mic-loudspeaker feedback) The echo is less if I use the 660 internal speaker. If I google "garmin bluetooth echo" there are many similar reports, with some sources saying using an external mic is the answer. But I don't have one at the moment.
I phoned garmin support today, using the 660, so he could hear the echo. He agreed it was bad, and said he would inform his supervisor, but also sent me a new file to replace the existing one in the remotesw folder in the garmin folder. But the file is the same size and same name as the existing. Should I go for it? I notice other users have trouble as soon as they mess with the files on nuvi.

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

Hi, Irene Garla!

When did you start experiencing this type of issue from your cordless phone? Usually you get echoes of your own voice when your base phone is on speaker mode. Either you get an echo or a feedback from the speakers from both units when you're on a call.
I hope this works for you. Kindly reply/comment for further assistance. Good Luck!


Thanks for using Fixya!

My sound is clear but caller on other end hears a echo of his own voice. HELP?


Its like calling into a radio station going on the air, and having your radio turned up while on the air you will always get an echo. Or at least a delay that other people will hear on their radio. it's the same way, with using a Car Bluetooth because they are hearing their voice coming through the speakers and going back into the microphone and then they hear that and there is your Echo. Unfortunately there is really nothing you can do except for ask them to deal with it :-(
