Well, I've just received mine too, and although I'm still awaiting a ferrite supressor (for the GTM itself), 10 minutes has shown some improvement...

There is no ferrite suppressor ring
Mine has a ferrite suppressor near the cigarette plug end, and it's part of the cable, so it wasn't added as an after thought
I still don't get a strong enough signal at home in the drive for traffic, but I did get it in the village, which I never have done before (I normally have to drive all the way to Milton Keynes and pick up a different radio station before it starts to work), so things are looking up (I suspect my local radio station may still be a little on the weak side).
I've got the same part number as TGL, which is also promising and yes, the old one was 10R-02 6017 and the new one is 10R-02 6025. Having actually just looked at the old charging cable properly for the first time since the day after I bought the 310D, I note it also had a ferrite suppressor near the cigarette plug end, but it was thinner and longer.
Monday will be the big test, with a nice long drive again.
Posted: Fri Sep 15, 2006 7:22 pm Post subject: When it works - it works
Just been on an 825 mile round trip from sunny Somerset to Amsterdam Eindhoven, via Harwich (which nuvi told me was nearer to Amsterdam than home).
Had TMC for what seemed like most of the way, but I did ensure that the nuvi was fully charged before each part of the journey (using original car adapter).
This was the first time that I used the nuvi & TMC in anger and I was well impressed with the way that it all works (when it works), so I'll be sticking with it and wait for Garmin to send me a replacement power adapter and whatever else is part of the final fix.
I think that a good test would be to let the the battery in the nuvi run down to about a quarter full and then try to get traffic information straight away with the new power lead in situ, if it does work then this would indicate that maybe the problem is solved.
If the battery needs to be fully charged before traffic info is received then there is still a problem.

It doesn't make any difference what state of battery charge you have. You either get signal or you don't depending on where you are.
I've had perfect results around Loughborough and up to J28 M1 but signal fails just after.
My cable from new was the 6025 and I did also get a Garmin supplied suppressor for the GTM12 but that made no difference either so I've taken it off. _________________ TomTom 740 Go Live
The state of charge makes a great difference, if I left my nuvi on charge I would get traffic info in about 6 seconds after switch on, if it was left off charge even just over night it would take a long time before the internal battery was charged enough for it to show any traffic info.
If you read through this thread you will find that this has thought to be the problem from day 1 .

Banjo12 ,
All I'm saying is that for me it doesn't make one hoot of difference how much juice is in the Nuvi battery. I've read the threads and experimented accordingly. Sat on my drive at home with an almost flat Nuvi Battery charge I can get Traffic signals almost in the wink of an eye.
So for me flat or full charge has no effect on ability to receive traffic signals.
I'm as keen to listen to and sort out this as much as everyone else but I can't see how or why this would make the unit sensitive to signal strength, not that I'm a techie in any shape or form.

The test here is to go into the secret menu and make sure you are receiving traffic messages all the time. It's ok saying you get traffic alerts and initially you may get 10 pages of it, but if the Nuvi loosing its Traffic signal, the blue traffic indicator stays on and the 10 pages of messages still stay there so dont get fooled that the problem has gone away (Double check).
My friend has a Nuvi 360 now with the GTM 12, and he has been reading this thread too. He phoned me and told me that he did not have the problems, but we did some testing and what I described above was happening to him. Traffic messages were not getting updated all the time, and therefore his traffic wasn't working like mine where I get a constant message count. If your Nuvi manages to get 1 message, the indicator stays blue indicating you have traffic alert, but 1 message it just plain rubbish.
So the test is, go it with someone else in the car and drive around with the secret menu showing the message counter at the bottom. In a strong signal, this count will always go up. If you signal level is above 7 and messages are always coming in on 1 of the channels, then you can finally say your ok.

I've been raeding this post and been having the same problems as everyone else has. I have a nuvi 360 with a GTM12 and it does not work in one car but gets some updates in my other car. Everything works fine in the house, but I made new observation today. The car that my traffic doesn't work in worked fine when I plugged my nuvi into a portable power supply. I think my vehicle doesn't have a "clean" connection to the cigarette socket and that possibly it could be alternator noise. Other than waiting for my new power supply that Garmin said they were going to send me, what do you guys think? Would there be a way to reduce or maybe even get a better ground on the lighter sockets?

I'm with you on this ColinG. I think I have the same charger as is now being supplied. It has a red led and built in ferrite next to the power plug (car end). I was supplied with this charger originally. I have never had a problem receiving a signal due to voltage or charge state of the battery, just lost radio signals. As ColinG says, after junction 28 M1 northbound, the signal suddenly cuts off. This occurred first about 6 weeks ago. I have made trips south recently and traffic worked perfectly, but as soon as I got home past junction 28, off it goes again. I defy anyone to receive a signal in Yorkshire (Galaxy FM area). It is obvious that they are not transmitting the required RDS data.
The whole 'battery charge' issue is due to the theory that if the Nuvi was fully charged more power would be devoted to the TMC receiver and traffic reports could be received. If it wasn't fully charged some of the 12vDC power supply would have to be used on charging the battery and so the receiver wouldn't get enought juice to work properly.
The newer power leads may have partly solved this but certainly past anecdotal evidence appears to back up the low battery charge/poor TMC reception theory.
Take your Nuvi in your Car and plug into the usual Lighter Adaptor
Stick the Arial Leads anyone on your front screen.
Now turn on the Nuvi and Hold your hand on the LEFT hand side.
Voila, my friend gets perfect traffic,
Stick the Nuvi on the Windscreen and let go and he looses traffic.
Moves his hand and touches the LEFT hand side of the Nuvi and Traffic Returns.
I tried this with my Nuvi, and my Signal level increases when I touch the left hand side only.
I like the sound of holding the left side of your Nuvi whilst in the outside lane.
Off topic slightly - had an email from Tomtom who expect their RDS TMC to be released at the end of September. Nuvi still looks better but if it doesnt work...

Would be interested in hearing your views if you do go for the TT1 v2. I think there are a few of use here (RDS?) who are adopting a wait and see approach after being dissapointed with the nuvi.
Cheers - Nick
Well I was going to wait and see - but I visited Halfords last Wednesday to have a look at the Tom Tom one V2 and ended up purchasing one!
I've used the product over the last few days. My option is it is far superior as a GPS unit.
1. Searching for destinations - post codes, addsesses, city centres, browsing maps. Whilst in France on holiday this year we met up with friends and wanted to visit the centre of La Rochelle. Neither of us knew the city and couldn't find on the Nuvi the city centre. Must have spent 15 - 20 minutes trying then got out a Mitchelin guide to find a street name. On the TT no problem :P
2. TT has option to display POI categories on the display.
3. TT has far more information on the drivers display.
The TT one V2 gets my vote and was half the cost of the Nuvi 310D. Admittedly I don't get TMC with the TT - but then even when it was working on the Nuvi it failed to inform me of traffic congestion when we had been sitting at a virtual stand still for over 40 minutes.
Also I don't get the DVD of Europe - but I can add at my leasure.
Fully converted to TT - so will monitor TT forum from now on.

Not true, if the unit can't pick up any traffic information at all then after a while (*), all traffic will disappear, leaving just a list of roadworks. If it's picking up a traffic radio station, but not keeping connected to it to allow it to read the traffic, it will remove all traffic and go back to "Traffic Data not available", and turn the blue icon grey again.
It would be nice to have an indication that the signal is still being received like the elder GTM units has (LED on them), or within the software (like the 26xx units did - a signal strength screen). But again, like everything, once they fix the problem, it won't matter so much!
(*) I've no idea how long "a while" - probably over 15 minutes based on my limited (**) experience of this.
(**) I've experienced it many many times, but rarely whilst driving have the time to stop and play with the Garmin, so although I've regularly seen the traffic disappear to either just roadworks, or to no traffic at all, I don't know how long it takes.
