Yeah, I meant the only place the TMC works...

I did find a couple of others this morning... It works half way down the slip road onto the M4 east bound at J8/9... Not at the top, and not at the bottom... Just the middle.

It works on the bridge over the Thames between J8/9 and J7 on the M4...

It works on the A4 somewhere between J5 of the M4 and where it (The A4) goes over the M25...

I got 9 messages out of that lot... 6 from the J8/9 sliproad... 2 from the M4 and one more before I got into work...

It was easy to monitor given I was sitting in an instant carpark all the way... Rather sadly none of the messages I got seemed to include the stationary & stop/start traffic on the A404(M) or M4 this morning...

Might be worthwhile trying to reposition your TMC or asking Garmin for a replacement as I drove on the Western section of the M25, M4 and M40 this evening and picked up the traffic all the way - 13 pages of it at times so Ver 4.00 definitely works for me

Not only try re-positioning the aerial lead on your TMC - but try connecting it to an external aerial - car radios are very bad at receiving radio signals in the FM band inside a car.

I'm having exactly the same issues as Hamie - M4, A404 Sad

I think its just poor reception

I can get traffic information in my back bedroom, unfortunately it doesn't lock on automatically, I have to do a manual search.

Once locked on I get the traffic but as soon as I move the aerial and try and move downstairs no updates.

Well, having got 2 messages one morning, and then 7 the next morning, I am now getting 170 odd messages before I leave my village (a first!). However, as soon as I head cross country towards Hertford (and hence change to a new radio station area), my traffic unit loses all traffic, and never recovers. Irritatingly, it never gets any traffic on the way home, even when back in the village.

So, I wonder if either:

a) There is a network outage in the Hertford area (although there wasn't last week when I used my other traffic unit).

b) The v4.00 firmware can't cope with you changing areas.

Even with my aerial splitter and amplifier - I don't get a blue diamond for about a mile from my home whereas in the earlier firmware versions I was getting traffic almost from my home.

This morning I've driven from Hampshire along the coast to Kent and then up round the M25 to Heathrow. For safety sake I'm not checking constantly but when I looked I was getting pages of traffic, so assuming that I am changing transmitter coverage areas this doesn't seem to be an issue. Can't comment on poss Hertford outage.

Hamie, as you can see from many of the contributors here, the GTM21 and new firmware clearly works perfectly so I think that you need to look at antenna placement or return the unit for a replacement.

I've got a Range Rover with a heated front windscreen. And Have a hard time getting any kind of signal on my 660. I was thinking about the aerial solution, and hear lots of people mention about attaching it to the car aerial, but no one ever says how Smile

. Could someone give instructions for this or point me to a website where I can find the instructions?

Thanks,

Jas
