Manufacturers description
Overview

Keep on the move with free traffic alerts and re-routing. There’s nothing more frustrating than being caught in traffic. This is why Navman makes TMC (Traffic Message Channel) available on most of our sat nav devices, either as standard or as an optional accessory.

TMC is a system for alerting you to traffic problems on major roads and optionally re-routing you should you wish. Delivering real time traffic information to your Navman via RDS-TMC (Radio Data System - Traffic Message Channel) – an FM based radio signal – you can see and be alerted to known problems such as accidents, congestion and roadworks.

Your Navman will also prompt you to revise your route – or even re-route you automatically to take you on the best alternative route to your destination

Lifetime subscription – no additional costs Best of all, once purchased in the shape of a T1, T2 or B2+ module (sat nav model dependent) the TMC service is free, for life.

Available for all current products.

Traffic can be added to specific Navman sat nav models as follows:
S90i Built in as standard – nothing to buy S50 & S70 Purchase the T2 Foldable Windscreen Mount (with built in TMC) F20, F30, N20, N40i & N60i Purchase the T1 Traffic Pack or B2+ Module if Bluetooth is also required F40 Purchase the B2+ Module (replaces the supplied B2 Module) F50 B2+ Module supplied as standard – nothing to buy

Customer Reviews

T1 Traffic Module Is A Safe Buy
I bought the NAVMAN F20 SATNAV last Christmas, and I have been entirely satisfied with its performance. However, on the basis of the first review I did not purchase the T1 traffic module. After running into several jams and hold-ups on the road (I cover between 50,000 to 60,000 business miles per year) I decided to go ahead with the purchase anyway.

The first review is particularly misleading when it comes to the installation of the antenna, and the coverage area of the T1. Firstly, the molded rubberized antenna was very easily installed just below the windscreen mount for the F20, the antenna itself is less than a foot long and is not unsightly.

The antenna lead can be neatly coiled and positioned on the dash. The orientation of the antenna, either vertical or horizontal will not affect the systems performance. Any signal reflection from intervening terrain or buildings that occurs between the transmitter antenna and your vehicle antenna will effectively reduce any polarization issues at the receiver antenna to an indeterminate state.

So go ahead and install the antenna in a postion on the windscreen in a manner that is both functional and esthetically pleasing.

Just how tidy the install is or is not will a direct function of just how careful the installer is concerning the finished aesthetics.

No; I don't go through the hassle of pulling down the installation each time I leave the car. The F20 unclips easily from the T1 and mounting cradle, leaving the cradle T1 and antenna in place. Just how comfortable one feels about this is entirely personal.

Most would argue that merely leaving an empty cradle on the windscreen is enough to attract vandals. This is dependant upon the area you live in, and the security arrangements at home and at your business destinations.

The road traffic data rides piggy back on existing FM radio transmissions as a separate digital data sub-carrier, and the overall coverage area will be subject to similar constraints of traditional FM radio channels.

The CLASSIC FM network of FM radio transmitters is the only network in the UK that transmits ITIS traffic data information compatible with most after market SATNAV systems in the UK. As you drive around the UK your T1 traffic module will automatically scan and lock to any of CLASSIC FM's UK mainland transmitters, based upon signal strength.

CLASSIC FM covers 90% of the UK mainland using the following terestrial transmitter sites:

The T1 is no different to any FM radio concerning reception issues. I work out of London visiting work sites as far South as Wimborne in Dorset, and as far North as Glasgow in Scotland. Keeping to the main roads and motorways, the T1 has never missed a beat.

However, it does have a hard time in the wilds of Lincolnshire (Blyton, my home village).

When travelling in or around London, the T1 is worth its weight in gold!!

Nothing in this world is perfect, but the T1 is worth the money, and will payback the professional user many- many times over in time saved, and frazzled nerves.

It's a no brainer, the T1 works as described in the manual, and the purchase should present absolutely no risk to both the casual and professional user.

Doesn't work everywhere - BEWARE
The TCM channel that uses Classic FM's frequency suffers from extremely variable signal strength (not comparable to how well you receive Classic FM either I'm afraid). So depending on where you live this may well work well - OR NOT. My daily commute is between Surrey and Hampshire via the M25 and the M3, I get no signal whatsoever until I am 10 minutes from my destination, which is useless.
Apparently the signal can be boosted by purchasing an external aerial (not avaiable from NavMan) and a cable adaptor, but is it worth the faff?
The unit also suffers from two basic design flaws. Despite boasting "integral design" the external aerial has to be plugged in and fixed inside your car. This is done by sticky pads (supplied), unfortunately the connection to the T1 is delicate and may not last with repeated insertions and disconnections, however leaving it attached and on view as the manual suggests is sadly not an option with the spate of thefts from cars whenever a Sat Nav cardle is left in view, and now there is an extra cable trailing across your dash. Also the power cable now has to plug in to the T1 first and an adapter is supplied as the socket is different. This is sad as one of the good design features of the actual Navman unit is that a single socket is used for 'In Car power', 'Mains power' and 'USB connection'. It is also on the other side of the unit so the cable may not reach to the position you have become accustomed too. This smacks of a different company sub contracted out for the design and manufacturing .
In summary if you have a good signal this is probably excellent kit (bar some design flaws) if you live in a poor reception area it's just junk - and I cannot find out how you would discover which you are in advance!

I accept not perfect but perfectly acceptable
the criticisms of the aerial below are a little over reacting, I feel. Yes, there is a long snaking lead with a T-shaped aerial at the end, but this is easy to fold away and works perfectly well just chucked on the dashboard, no need for permanent mounting. The only quibble from this point of view is the adaptor needded to fit the power supply, wich I agree is silly.
However, the unit has worked well in conjunction with the F20 europe whenever I have used it: driving from the Midlands to London, up to Yorkshire and around the Midlands- no problms, picks up most delays and reroutes effectively. The only other irritation is the lack of instruction with the T1 or the navman F20 as to how to receive updates- the navman only gives you the options once the module is attached, which caused alot of faffing when we first set it up. However, subscription free and works well, so overall a thumbs up. I'll be interested to see how it fares on the Continent this summer...
