Garmin GTM60 HD Digital Traffic Receiver Service

 

I have a Garmin GPS that I use with the GTM60 HD Digital Traffic Receiver. Lately, I have stopped getting the data from the HD Radio Broadcast system.

Would there be any value in contacting Garmin to advise them of this? I realize that the data comes from an HD radio station, but I have no idea which one. Does anybody have any information on which station(s) might be providing this data. I am in the Minneapolis-Saint Paul MN area and my ZIP is 55068.

I am also well aware that I can get the data via the internet by connecting my smartphone to my GPS. I just like having this for the times that I don't have my smartphone with me.

I did also check and my area is not listed in the Current Traffic Outage area.

GTM60

Are you still getting traffic info in other locations? If not, it is possible that your GTM60 has simply failed and replacing it would hopefully resolve the problem. Do you know anyone else that has a comparable Garmin device and uses traffic info? That would be one way to verify whether or not it is still being broadcast in your location.

Garmin GTM60 HD Digital Traffic Receiver Service

I haven't traveled into another area that has HD Digital Traffic Service, so I don't know.

I have a second Garmin GTM60 with another GPS and it, too, does not receive the service.

This is the reply that I received from Garmin.

This doesn't help at all.

If I could simply find out what station the service comes from I would contact the station myself.

See http://www.rdslist.com/freq/89.php. Content is old but start by selecting the frequency of your known stations along the top.

Same Issue

I have two Garmin GPSr's which use the GTM 60 digital HD traffic cable. I stopped getting traffic reports on both about a year ago. I never pursued the issue though since I now get traffic reports via Smartphone link.

I just assumed that the local FM stations in my area stopped broadcasting the signal.

BTW, my brother, located in another state, also had the same issue. He replaced his GTM 60 but it didn't solve the problem.

It would be nice to have HD traffic via the GTM 60 as a backup but I'm happy enough with the traffic reports I get with Smartphone link using Wase as a backup.

However, I realize this is not an option for folks who don't have a smartphone or choose not to carry one.

FM based traffic receivers.

It does make me wonder just how much longer the FM based traffic will be a viable option. Those of us who have been on this forum a long time remember the hubbub created when the MSN premium traffic service was dropped. Those who paid extra for devices with the MSN receiver were very upset and even threatened a class action suit against Garmin. But like most threats of that nature, it was just talk and never went anywhere. Smartphone technology has made many established technologies decline and become obsolete. I suspect the FM based traffic service will soon be another one.

The FM traffic was never of much use to me because of its limited coverage. There is NO coverage where I live or where I have done most of my driving. On the other hand, the Smartphone Link traffic coverage has been very good, although the accuracy of it is sometimes questionable.

Although...

Smartphone Link traffic is far and away better than FM HD traffic but it requires a cell signal which can also be spotty or non existent in rural areas. Thankfully, so is the traffic.

True

True, but where cell service is spotty or worse, FM and HD traffic has never existed and likely never will. Large swaths of the Southwest have no FM/HD but still have some areas of cell service. I traveled Northern AZ, southeast UT and CO on state highways quite a bit and was surprised that at least along highways, cell service was found more often than I expected.

Very True

My wife and I just got back from a trip to Colorado & Utah. We were rarely out of cell coverage. Areas that had none when we were there two years ago now had service. Progress is definitely being made.

GTM60 HD Digital Traffic Receiver.

I have the NUVI 3597 but I am not sure that it uses the Digital Traffic receiver. How do I find out this information?

If it has the GTM 60

If it has the GTM 60 Receiver Power cable, it does.

If you purchased your Nuvi 3597LMTHD new or factory refurb, it would have come with the GTM60 power cord/receiver. I have two 3597's. One was a used unit bought on Ebay and it did not have the GTM60 included, but if I plug my GTM60 from my other unit (a factory refurb) into it, it will receive HD traffic. I no longer use my GTM60 power adapter on either of my 3597's because I prefer the Smartphone Link traffic and the GTM60 cord is so bulky. I power my 3597's with a standard USB cord and a USB adapter plugged into my cig. lighter socket.

Per the Garmin website, these are the GPSr's compatible with the GTM 60

The Nuvi 3597 is definitely compatible.

Garmin GTM60 HD Digital Traffic Receiver Service

I tried a different Garmin this morning and I did get the HD Digital Traffic signal. I need to so some more research, but if I recall correctly, the ERP (Effective Radiated Power) of HD radio isn't all that great. I live over 20 miles away from the Shoreview Minnesota towers, which is where many, perhaps most, of the FM radio stations broadcast from.

From Google:

How far does HD Radio signal travel?

No, unfortunately—the HD signal has nowhere near the range of the standard analog signal. In my own experience, an HD signal is only remotely reliable within the immediate environs of an urban area, becomes intrusively flaky around the 10-15 mile range and is basically unusable beyond 20.

Good troubleshooting.

Sounds like you have done some pretty thorough troubleshooting. Glad you have made some progress on the diagnosis.

Interesting thread. I too

Interesting thread. I too saw my FM traffic die about a year ago and never went to any trouble to troubleshoot, just assumed it died. I found it useful on occasion, but more just thought it was a cool free service.

From an area where the signal/service is strong

I live in the DFW Texas area where both HD and non-HD have strong signal and excellent coverage. I have the GTM36 and GTM60, used both, and this is how things work with traffic when the area has active strong signal:

Using the nuvi 2599LMTHD with the GTM60 that gives you everything and the kitchen sink: Yes, you get more traffic notifications to the point of it being somewhat annoying. Yes, you get the not-really-useful 6-day weather forecast (no radar). Yes, you do get the current outside temperature. Yes, you do get some additional reports for "major city streets".

Using the Drive 52 with the GTM36: Notably quicker to acquire traffic updates and wider coverage range compared to the GTM60.

In my experience, the GTM36 is the better performer.

The biggest compliment I can give to either the GTM60 or GTM36 is that yes, the nuvi/Drive when made aware of major traffic events will route you around it, if you have the setting enabled to do so, i.e. "Optimize Route" automatically. This does work, happens in the background and has saved my butt more than a few times.

same thing here

It is the same thing here, frostedside. The New York City metro area has good coverage for FM and HD traffic.

Recently completed a cross

Recently completed a cross country road trip and discovered that the traffic notices were sometimes erroneously reported or were not updated recently enough to indicate actual conditions. This was with a DriveSmart with the traffic cord and connected to a smartphone. I still find the information useful but do wish it was more accurate.

If you are connected via Bluetooth to the Smart Phone and have Drive/Smartlink running, your unit will not use the built in or connected cord traffic service It will always use the traffic from the Smart Phone.

That Traffic comes from Here, and is the same traffic information that is provided to area FM transmitters. however you will get a much broader coverage, since the local FM transmitters only send local information.
