Nothin' but a deafening silence.

Maybe the reception problems with the Nuvi/GTM12 are more than a simple power lead issue or maybe Garmin aren't taking it seriously.

Just done a webupdate. A new firmware uopdate for gtm traffic recievers is available (was not there a couple of days ago). Don't know the sw number as of yet but heres hoping it improves things.

Added menu option to change splash screen that was taken out in 2.70
Fixed route review page: correctly draw the new turn
Added minor translation fixes for Swedish and French

Does not look promising !

Hi Guys

I have received an email from Garmin UK and they said Garmin US are looking into the problem with the 12v supply and the GTM12. They are hoping a permanent fix will be availble in a few weeks but for the time being have indicated that using a suppression kit can improve the situation (not sure what this is?!) so fingers crossed that this might be resolved soon!

After updating to GTM3.6 at the weekend I received reception almost immediately this morning, even before the GPS! Unfortunately the messages soon dissapeared from the screen and the usual message appeared but according to diagnostics screen messages were still being receieved despite the signal being low (5/6). Restarted the Nuvi and this seemed to fix the problem and received TMC all the way to work. Will give it another test this afternoon.

Does anyone receive emails from Garmin regarding updates? I have registered but never do. If GTM3.6 is working for me I probably won't update to 3.7!

Banjo12 - if you return your Nuvi to Halfods please let us know how helpful they were.

Cheers -Nick

To those getting confused by the firmware updates, in the last day Garmin have released 2 new and different firmware updates:

- Firstly, they have released an updated firmware for the Nuvi 310/360 itself (v2.80) which fixes a number of little things introduced with the v2.07 firmware

- Secondly, they have released a new GTM firmware, moving it from v3.60 to v3.70, but unfortunately, Garmin do not provide any details on what they fix with these updates, so we don't know what's changed.

However, the v3.60 GTM firmware did seem to cycle through a whole range of frequencies, all the way from 1 upto 150 - whereas the UK radio stations are all in the 80-150 area, so producing a new firmware that concentrates the searching into the right band might be a good start (once people have a working power cable) Smile

Well, there's a possible solution to this whole problem coming, and it's coming from Garmin....

On another forum, someone received the following response from Garmin:

Thanks for that swing, but after waiting for two weeks for an e-mail response and hanging on the phone for 15 minutes today without getting through I am not pleased at all.

Perhaps a barrage of e-mails from all of us threatening to return these sub standard units might get some action ?

what do they mean "you will be glad to know that only the UK is affected" that is very good of them and if the design of these chargers has been altered, for the worse may I add, why can they not send us all a charger built before this problem.

This gets better and better.

I have bought a 310D in the last week and have been very pleased overall with its performance in taking me to Cornwall from Surrey and a few days around about in Cornwall. Receiving a traffic signal was very slow, particularly in Cornwall but once up and running was never dropped.

The unit was supplied with v.2.60 software which I have just upgraded to v.2.80 but where do I find the GTM version 3.70 upgrade? I cannot find it on the list of downloads available on the Garmin site. My unit currently shows the software version as N/A but as I said, I have used the Traffic feature with a reasonable amount of success.

The line noise answer seems interesting, I wonder if they intend to fit a ferrite bead to the cable, much the same as you get on your PC monitor lead.
