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.

Garmin GTM 25 charger cord has broken wire inside.


Most likely that is the FM antenna lead that goes to the traffic receiver. It should only be connected on the end that goes to the receiver.

You say the GTM-25 is not charging. Is the fuse blown? The charger takes +12VDC from the lighter socket and supplies +5VDC to the GPS.

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.

My GTM 20 tip got unscrewed and the parts fell out. I put the parts together and then found out that both the car socket fuse and the GTM 20 fuse were busted. I replaced both fuses. The car socket works...


The GTM 20 can be repaired. It's likely that either you're not using the correct fuse or there's a short circuit. The short circuit would be caused by the metal tip, spring or fuse touching the outer part of the plug. There's a repair kit available from http://www.gpscity.com/garmin-replacement-parts-for-gtm2x.html

Garmin nuvi / gtm 20 charger not working. I think it's a blown fuse. How to replace fuse?


If yours has a plastic tip at the silver metal contact, just unscrew the plastic part between the silver ring and the silver tip. Counter clockwise! Fuse should fall out but take cautions not to lose the silver tip part. I you do it can be found at www.gpsnstuff.com
