Two traffic updates for Nuvi (and possible others)....

Sorry folks but but my Nuvi 360 locks onto Classic FM and downloads a lot of traffic data which the Nuvi cannot use (details a few submissions ago).

This evening I went over to the closest RAC transmitter (Mercia FM) and was able to lock on and receive valid data. However, in the menu I still do not have the option of using RAC LIVE.

Back home again and the Nuvi again locks onto 126, which is 100.1 Classic FM, and download useless data. The FM channel quoted 102.6Mhz and later 970Mhz.

I can only guess that the download has messed up the FM tables of codes and checks and unless the RAC / Trafficmaster is the strongest signal we are going to have problems getting traffic messages.

Check your Traffic setup (in setup under Display menu). If the Provider is on Auto and you have the option to change to RAC LIVE - do so. My option is limited to TMC_INFO now and unless Garmin sort it I have problems.

Hi.

I too have had the same problems of locking on to Classic FM with tons of data, which Nuvi is unable to display.

My advice would be when receiving a popup asking if you want to set auto - Don't!

I've found a temp fix around this, but unfortunately you'll need to repeat it every time you power up.

From the GTM Status page, as soon as the first data appears, quickly select Test. This appears to stop the Channel scan. It obviously helps if you know which channel in your area normally gives you good traffic. If you don't get the correct one straight away, Select Norm, then Test again immediately, until you get the Channel you gives you Traffic data. If it selects the Classic Channel and won't let go, disconnect external power momentarily and then try again.

Once you get the channel which gives you data, it appears to lock onto it - until you disconnect external power. If you select Norm again, you may get Classic FM back if the comparable signal is much stronger, but leaving it on Test works ok. Not sure what happens if you leave area of this transmitter and it starts to search for a stronger one. I'll let you know when I find out.

Anybody told Garmin about this problem yet, as it'll obviously need a new software upgrade - again! Yawn

I have just purchased a GTM12 and while my Nuvi 350 recognises it I am getting the message "Traffic data not available". Has anyone had this problem and how do I get to the hidden pages, mentioned in this forum, to see signal strength.

Thanks

Bob

bobison,

Getting the Traffic messages is the major problem if you are not in a strong transmitter area.

To get the hidden information, from the Map screen, press the Speed box, then the central upper box - Moving Ave - for about 8 seconds. Press Next 6 times and you are there.

Just be careful what other boxes you press as we are not quite sure what they do.

Thanks for the info on hidden pages. Using the display I have found that I can get a great signal in my house with the Nuvi powered from my PC but it won't work using the car charger. Crying or Very sad

But I really appreciate your help.

You are best asking in the TMC section of these forums, rather than within a thread dedicated to the Garmin GTM21 unit.

Having said that, I think the answer is no.

Ever since I updated the GTM firmware last week my Traffic has died. The ' ! ' is permanently greyed out contrary to what it says on the diagnostic page Sad

. I'm getting sick of this...

I've also got the same problem with a Nuvi310.
Since updating the firmware to v3.90 a few days ago, my GTM12 worked the first time following upgrade, but not a sausage since.
My "i" is also permanently greyed out now whereas using 3.70 I had no trouble receiving traffic data at all.
I've tried both Auto & TMC_INFO, but neither works so far.
I think I was on RAC Live previously but didn't take much notice as I hadn't a problem !!!!!

I only have a back up of the 310 when I bought it on 18th December, so not sure whether to re-build it, or wait to see if someone comes up with a fix?

I tried my previous suggestion today on a journey from Bournemouth to Exeter. Worked ok initially, but then not much in the Honiton/Exeter area, which I know was previously ok. So I accepted the "would you like to accept auto" suggestion, and lo and behold, traffic appeared.

I left it on auto for the rest of the journey, and the return, but on getting close to Bournemouth, it unfortunately selected Classic FM 100.3 again, with lots of data, but no traffic, so back to square 1.

So is it a Classic FM fault?

Another way around I've discovered is, if you have one of those mini FM transmitters (now legal) for listening to your IPod on your car radio, select the problem frequency - in my case 100.3 - and it makes the Nuvi look for something else. After a while I switched the transmitter off, and all ok.
