Newbie Needs Help With GTM21

I recently purchased a C510D, complete with traffic receiver. I have registered the nav unit with Garmin, but I was wondering if I have to do the same with the traffic receiver. I tried this, but the GTM21 did not appear as an option on the MyGarmin site.

I dont know if I have to activate my Trafficmaster subscription or not. So far, although sat lock has been very quick, I have not got anything but a solid yellow status light from the GTM21.

I tried searching for traffic providers, but this just kept going on and on with no providers returned. I note my subscription appears in the relevant section, but I always get a message saying that it has not been activated, and will do so when it actually receives a broadcast.

Any thoughts would be greatly appreciated!

Oops, meant to say that I am in west Leeds. Anyone know what the traffic coverage is like around here?

Hi Stuart

I have also bought the C510D,and when im sat at Home in the car with power running to the GPS, i also get a solid Yellow light,and it comes back with no search results

I drove into town centre and the light went green.you can also try driving near a motorway as they have lots of transmitters.
I then did a search with the light on Green and it came back with 2 results

1/ RAC Live: Lifetime Subscription
2/ V-Trafic: Not Activated

But when i click on the subscibe,it says im not subscribed to any and to go to www.garmin.com/fmtraffic and to enter my unit number.

I did go to there website and i enterd all my details on there form and it came up with Traffic master lifetime subscription $60.
which i dont understand because its suppose to be free

So i dont know if the RAC one is the automatic active one or
garmin have done somthing wrong on there site..

But aslong as you have the gps unti switched on with the powercable/transmitter cable plugged into the power socket
and the back of the unit, try driving to a motorway bridge and doing a search there once the light goes green, and see what comes up

Took a spin along the M62 this afternoon, with no joy. Mind you, I was watching where I was going rather than the status light! I did try to do a search near a particularly infamous (from a traffic point of view) junction where the M62 meets the M1, and still no luck Sad

paul ,tmc works off radio transmissions ,normally on the classic fm frequency...the blue poles you see on the motorway and 'a' roads are traffficmaster poles which work different..there are lots of threads re a problem receiving tmc and apparently the m4 corridor is a pretty bad reception area.. rac subscription is free, v traffic is the french version and should work when you are in france..

Just been reading about the TMC problems others have had. Kind of depressing, as my justification for buying a Sat Nav in the first place was accurate, reliable traffic.

Starting to wish I had opted for the TomTom one instead. Their GPRS service is pricey, but at least it is reliable by all accounts.
