Question about Garmin GTM 12 FM TMC Traffic Receiver Receiver

Malfunctioning Garmin GTM 20 fused GPS power adapter

The rubber plug to the pin connector which gets inserted into the unit is loose and about 1/8" of the connective wiring is showing.

Upon removing the 2-screws on the connector casing, it appeared that 9-wires were secure (2-red, 2-brown, 1-purple, 1-green, 1-blue, 1-yellow, 1-black) but there was a small amount of loose stranded wire by the foil wrap at the power adapter end which is fused for traffic reports.

After reassembly the unit would not work off the adapter-- the fuse (3A) blew either before or after, but before I replace the fuse and try again I would like to know if the loose stranded is normal or if not, how to correct it.
THANKS

The two red wires are +VE Supply and both connect to pins 1 and 2

The two brown wires are Supply Ground and both connect to pins 8 and 9

Pins 3 through 7 are the traffic recievers digital interface:
Purple/violet connects to pin 3
Yellow connects to pin 4
Blue connects to pin 5
Black connects to pin 6
Green connects to pin 7

I found out from a Garmin rep that Garmin will swap out the adapter if you send it in. The only cost would be shipping charges. It was too late for me as I threw mine away thinking that it was not working realizing later that it might have been a blown fuse

I believe the loose strands are normal. My connector end has been stretched out but the cable still provides power. What I need to know is where the blue, green, and black wires connect to on the terminal (GPS end), as they have been pulled apart. I get power but no traffic info. It's a 14 pin terminal. If the brown/brown is connected to pin 1 and red/red is connected to pin 8 (ie: the flip side of pin 1 is pin 14), could someone tell me which pins blue, green, and black connect to? (I'm guessing black is ground and is connected to the terminal body.)

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.

I have a Garmin with a GTM 20 traffic receiver p/n 010-00544-13 and I wanted to know if there is a fuse that can be changed and how do you do it?


The GTM-12 is an antenna including FM receiver - there's no fuse in there. It's powered by the Garmin navigator not from an auxiliary power source.

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

Looking for a wiring diagram for a garmin gtm 20 traffic receiver. A couple of wires pulled loose.


Just so happens that my connector lost the red and purple wires, so the picture you have was a great help. Looking at the connector, the wire colors are red, purple, yellow, blue, black, green, brown.

Garmin gtm 20 lost tip and spring can i get replacement parts


The garmin.com/parts won't get it. You'll have to call the 1-800-800-1020 number and press the number for the automotive service option. After that, you'll have to wait another 30min ( I waited 90 min - home waiting on the cable man), then you'll finally get to a person who will take all of 60 seconds to place the GTM-20 tip kit on order for you. The service person said that it was a common problem, but don't know why it's not on the Garmin site to order on line. Total parts and shipping $11.50. Hope this helps.
