It looks like the traffic receiver is now available. I just ordered mine for two day delivery. I'll let you'll know how it works out; at least for the Hartford Ct. area. |

Any other FM TMC Users from Austin, TX here? I've been in contact with the Clear Channel folks, and want to see if I'm the only one seeing what I'm seeing.
Thanks!

I have had a GTM -11 for 10 months now and am starting to get intermitent check trafic receiver warnings. Anyone have a GTM that failed? Or is there something going on in the network? Indicator light stay steady yellow. |

I have both a GTM10 and 12. They seem to work the same. The GTM10 has a led indicator to provide feedback as to its status. The negative is you need to insert the unit in the car antenna path.
I purchased the GTM12 so I can have the traffic receiver when I travel. By the way I use a 2720. If you are going to purchase a receiver I reccomentd the GTM 12. It is physically very small and has a flexable wire antenna attached that is convenient.
The real problem I have with the current traffic system, at least in the LA area is Clear Channel keeps turning off the subcarrier carrying the traffic data for periods. This means if you turn on the GPS and set up a route it will not be able to take advantage of the traffic information immediately. It can take up to 10 minutes before you get your first data set.
Hope that helps in your decision.

This is a crosspost from another thread, but I thought it should be included in this GTM10 thread as it is pretty good. I will talk about two recent incidents regarding traffic reporting on my 2730 which were very positive.
On Wed this week I was driving into work. At 5:50am there was a 5-6 car accident immediately in front of me -- about 15 cars ahead. The cars blocked all 4 lanes of the freeway in my direction, and everyone behind came to a complete stop. Within 2 minutes, my 2730 turned red on the path I was on. An "accident" icon appeared, and upon 'review' it said "Broken down vehicles blocking roadway". As the minutes passed, I saw the red describing the freeway speed on my 2730 grow longer and longer behind me as traffic behind me came to a stop. Within 5 minutes I was able to pass through, so I didn't have to sit too long.
I reported this event to my brother, who asked "it took 2 minutes? why wasn't it instantaneous?" I told him the unit is not omniscient; the accident needs to get reported to CHP and the flow data needs to propogate through the network, through XM, and back to my receiver.
Another similar accident occured this past Sunday night, only this time I was about 5 miles behind. The unit routed me on some convoluted backroads. Other people with late model luxury cars were following these same backroads, implying (to me) their cars were directing them too. All along our parallel route, we saw traffic stopped dead for miles. Our units directed us to get back on the freeway immediately after the accident. The unit performed splendidly.
All in all, I have been very pleased with the traffic reporting in my area. The unit's shortcomings over the 26x0 series, however, are a PitA. |

My thoughts are that the XM coverage map shows that flow information via the XM service is not available anywhere in Connecticut. Only incidents are reported. Looking at the FM coverage map, a large number of highways throughout the state are covered. |

Did anyone change from getting traffic information from FM TMC to XM Navtraffic? I live in the Hartford Ct. area and when I used FM TMC traffic was pretty acurate for the most part. Now that I'm using XM Navtraffic I see almost nothing on my commute (even though I'm stuck in traffic). I do get some traffic but nothing like FM TMC did. You thoughts? |

thanks- I have been there. of the 3 streetpilots I have considered-
2720, 2730 & 2820 it seems the 2820 includes the XM ant (built in) but then product descriptions say differently.
I also wrote to Garmin last week- still no reply ! |

Best to go to Garmin's comparison page at:
http://www.garmin.com/products/comparison.jsp
But from what I recall before I bought the 2730, they're basically identical except that the 2820 has Bluetooth capability and has capability of decoding both XM and FM traffic data (after purchasing a compatible receiver) while the 2730 does not have bluetooth and can only do XM data (but it comes w/ an XM receiver and antenna). The 2730 also has FM transmitter capability so that output can be received over you car FM radio (quality sucks though if you live/travel in a saturated FM market). |

p_synthesis - what about the 2820? - I typed in error 2860.
Whats the diff between the 2730 & 2820 ? |
| p_synthesis |
Posted - 18 oct. 2006 : 19:33:02
The 2730 comes with the XM Antenna. Yes, it's another thing to hook up to the unit but at least you don't have to buy a separate GTMx or XMx antenna. |

No. None have anything but built in gps Antenna. Some of the units have the Fm reciever built into the power cord e.g. the C5 series both included with C550 and as option on C530.
This is a nice hook up arrangement as it is one less item to plug in.

So the 2860 does not come w/an XM built in antenna? |

The 2820 and Zumo are the only two units that offer both XM and FM I hope that this eventually rolled out to all gps garmin or otherwise. Each has their strengths and weakness and cost differences. FM has more locations/cities. It is not clear whether the actual coverage in cities that are shared in common is better with one verus the other some users have reported such with XM being superior others not. They should be fairly similar.
Both require an External reciever antenna which can be mounted inside the car or in the case of XM outside too. If you were not planning to have XM non Traffic Xm costs more. But in the scheme if things if one is paying to avoid traffic then one might not care.
Keep in mind no unit is going to know about all traffic, just like traffic new radio does not.
