A group of italian hackers has demonstrated a way to send out fake TMC messages. What started off as an April Fools day joke has now been demonstrated to actually work, and with relatively little effort. Think about a disgruntled local establishing his or her own private radio station to tell motorists of a permanent accident around his/her house...

Interesting to read that something called TPEG should be replacing TMC sometime. Interesting to see how that will work and if existing hardware will be able to use the data.

Hmmm been in development since 1997, so maybe still sometime before the existing system is replaced. Also seems to be DAB radio broadcasts which can be just as hard if not more difficult to get a strong signal on?

Also, of course, a DAB based solution means all new hardware, and you would definitely need an external aerial DAB connection. I'd prefer the UK companies to concentrate on improving the current TMC solution Smile

I wish the RDS-TMC recievers that are currently available had an external connection to feed them with a decent signal, they might start to work a little better - Mike

How difficult would it be for car makers / gps makers decide on a standard connection which the car would have and the GPS plugged into it and gave access to the aerial on top of the car, sorry but I'm not prepared to take my car apart or trail unsightly wires all over as a perminant solution. I don't like having to trail a wire over the screen as it is.

Yes the only time I got any info on mine was when I was stuck in a jam itself. The first time it ever worked and I was already stuck!

So do most of the RDS-TMC units I use, but I have had to modify them with a soldering iron to achieve this, the Navman product looks good though at least it is supplied with an aerial and the capability to connect an external feed via the socket - big plus point having the connection fitted to the device, looking forwards to seeing how well this T1 works in the NW of UK - Mike

I have had no problem at all with mine. I bought a magmount aerial from Maplins and a Garmin BNC to MMC to make the connection. Wires everywhere at the moment, but I have no difficulty in getting a good signal...dead spots on occasion, as the coverage is patchy in the UK. Hoping for something better when I travel around europe, particularly Germany. Wink Pity there is no other transmitting station in the UK other than Classic FM. - Graham

OMG YOU GUYS ARE USELESS!!!

TMC works a treat if you would just read the instructions and fit it in your car properly.

Im running TT 910 with the 69.99 RDS/TMC adaptor for my work EVERY day and for personal at the weekends and evenings and the TMC adaptor give me info ALL the time.

Remember that updates only appear every 15 mins and there may be nothing to report. Not every que will be on there if the traffic network doesnt know about it. And if you are getting NOTHING... they maybe use your brains and check why, a penny to a pound it coz you installed it all wrong!!!

I wont have my TT connected anymore without TMC as it works so well so the rest of the world (PocketGPS) must be doing something seriously wrong!!!

READ THE INSTRUCTIONS!!!

I am not even going to answer that part!

Perhaps you could inform the forum exactly where you find it works so well in the UK, and what vehicle you are using it in? - I can assure you there are plenty of us that have jumped through hoops trying to get this to work and got nowhere. - Mike

Sound like a troll to me....

Moderators be my guest, kill this thread, at the very least lock it!

Re other comments:

OMG YOU GUYS ARE USELESS!!! Clearly we all are?

TMC works a treat..... wish it did, even TT acknowledge it's near useless.

maybe use your brains ... cannot do that i'm way to stupid.....

READ THE INSTRUCTIONS!!! ... You're not supposed to be able to read are you? That's clearly where i'm going wrong.
