You have to have the traffic receiver / car charger in order for it to work (GTM-20) It looks like this:

It has a green LED for power and and an alternating yellow/red LED for traffic data detection.

Yes, you have to have a subscription to the service.

Will a garmin gtm 20 charger work with a garmin nuvi 660 gps

Yes! The GTM-20 is a charger with a built-in traffic receiver. The charger plugs into the cradle for the Nuvi 660 and then the Nuvi 660 snaps into the cradle.

However to receive traffic with the GTM-20, you will need to purchase a subscription, either yearly or lifetime. The traffic receiver receives traffic information from FM radio broadcast stations, which broadcast traffic data.

My nuvi 660 seems to have "lost" the traffic portion . When I touch tools and go to look for traffic - or "settings" there is no settings . Could it be the GTM-20 FM transmitter is bad?...

If the GTM-20 Traffic Receiver is functioning, you should see a blue diamond on the main screen and you should be able to find a traffic icon in the menu.

If the diamond is grayed out, then the traffic receiver hasnt locked yet. If the traffic symbol is completely missing, then yes it could be a problem with the traffic receiver or the cradle or plug that plugs into the cradle.

The Nuvi 6xx receives traffic information from the GTM-20 receiver through the plug that plugs into the cradle.

Update maps for nuvi 610 sat nav for free

Garmin stopped providing FREE map updates for this device in 2008 - in fact they don't even provide software updates anymore.

However, for the same price as Garmin charge for their latest map update, you can buy a brand new device (not Garmin though) with wider-ranging & updated maps.

OK... so a cheap GPS device might not have Bluetooth, but the Garmin nuvi 610 fails to work with a lot of the newer phones on the market today (e.g. Nokia N95, etc.), in that the phonebook and SMS interfaces do not work.

The biggest problem with the 610 is that you cannot 'hack' the OS. Therefore, you cannot simply load new mapping software such as iGo8, which is far superior guidance software to the 610's standard software. Also, you can’t download amusing voices or anything fun like that.

Also, the 610 has many software bugs. On occasion, the security start-up screen will automatically by-pass and take you straight to the main screen – a serious flaw. Also, the currency converter cannot accept new currency rates, rendering it useless.

Regarding the traffic report system... well, don't bother I say. Unless its major pre-planned roadworks, it never lets you know when there's a jam up ahead. You are better of tuning your car radio to a local station to get traffic reports.

All-in-all, the Garmin nuvi 610 was an ill-fated, buggy, incompatible, and expensive option. I only use mine as a backup device if I'm out for a ride on my motorcycle and get lost on the back-roads.

Traffic reciever not working with Nuvi 650

I have the Nuvi 650 (for about a year now) and just bought the GTM-20 traffic receiver. This receiver came with the "free lifetime" traffic service. (Keep in mind that at first use, the receiver is "mated" to the Nuvi for "life". You can't move it to another GPS).

In any case, the GTM-20 manual says you only need to plug the two together and the two units will establish their connection automatically.

Mine didn't work.

I called Garmin and after a LOOONG hold time, finally got through to a tech rep. She advised that I connect my 650 to my PC and login to Garmin to check for upgrades. She was right. When Garmin offered this "free service for life", they had to issue a new software update so the Nuvi would accept it. She also advised I check the offered "optional" upgrades as well, and look for any that offered "traffic" in the title. There was one of those upgrades, also. (almost everything else was optional "voices" downloads).

I downloaded both the primary software update and the optional traffic update to the 650. It installed them automatically. She also advised "just to be sure" to do a hard reset on the 650. That involves turning the unit off. Then, while pressing a finger in the lower right corner of the screen, turn the unit back on. The unit will ask if you really want to risk losing personal data.. Say "yes", and the unit will do a clean reboot with the upgrades.

Reconnect the receiver and the 650. It may take awhile for the units to acquire the satellites, traffic signals, and set the internal key, but it did work. You may not see the "traffic icon" at the first map screen. If you go to the tools or setup screen, you should see the traffic icon at the lower right of the screen. Press that, and if you are in a coverage area, it will show traffic in the area.

If you have the first version of the GTM-20, you will have a set of LEDs on the power plug that show power and traffic signal info. If you have the new version of the GTM-20, there are no lights on the plug.

A couple of side notes. If you have a lot of "favorites" saved in your 650, you may lose those on the hard reset. To avoid that, put your 650 on the PC, go to your file explorer, and go to the "Nuvi" drive. Click on that, and find the the folder and file called "gpx". Copy that to a folder or desktop on your PC. After you do the nuvi reboot, reconnect the PC and copy the file back into the folder on the 650. That will restore your favorites.

Also, make sure you are in a covered area. If you are not, it won't find the signal and will not show you any traffic icon.

The first time after the upgrade and reboot, the Garmin rep said it could take anything from several minutes up to nearly an hour for it to establish the link (mine was about 10 minutes). After that, it will come right on.

A lot of information here, but the first thing is to get the latest software upgrade for the 650. I had upgraded mine about 4 months ago, and it was already two versions out of date. The newer version had the fix for traffic. I would start there.
