Garmin nuvi 3790T - Traffic Features and Verdict

By James Morris



Our Score:


Traffic updates are available, too, but these come via the traditional RDS-TMC system, delivered by FM radio, as there is no mobile data facility like the Garmin nuvi 1690. So the 3790T offers no live services. There’s a traffic icon on the map screen that you can use to browse a list of current traffic incidents or get details of incidents along your current route. Traffic updates can also prompt rerouting, although the level of detail is not as great as TomTom’s HD Traffic, which covers a greater number of UK roads.

The 3790T’s windscreen mount includes all the electric connections as well. So you only have to clip the device on and it’s ready to go. The aerial for the RDS-TMC FM radio receiver plugs into the car power adapter, which then attaches to the mount. It’s a convenient system, although not quite as seamless as the magnetic mount provided with TomTom’s GO 1000.


The Garmin nuvi 3790T is one of the few sat-navs we’ve come across that elicits desire before you’ve even turned it on. Fortunately, when you do, the attractive looks are matched by a capable set of features as well. If you’re a regular rush hour commuter or travel frequently for business, we’d still recommend a TomTom device with HD Traffic, as this is noticeably more effective than vanilla RDS-TMC for avoiding jams. But if you want a beautifully functional sat-nav with particularly good voice control and on-foot capabilities, the 3790T fits the bill very well indeed.

@Wayne Harris Actually, yes, you would be mad! If you've still got the LIVE services on the 940, it will be a pretty handy device. Much more chunky, but very effective.

On the Amazon review front, I only found a few negative reviews when I looked. I agree that rerouting and route finding is slower than TomTom, particularly the GO 1000. But I didn't encounter any instability or crashes during testing. The 3790T was pretty dependable.

Hi james, i really can't make my mind up between this and the tomtom go live 1000. I hear the 3790t has issues when acquiring satellites? i'm also concerned that people say the 3790t cant get you from a to b? i've never had a sat nav but have found both are now within £10 of each other,which would you rec? many thanks

I have a 3790t and I've not had any problems with it acquiring satellites when outside or in the car. It's been very reliable. As for getting from A to B, again, I've not had any problems.

I am underwhelmed by three features of my 3790T.

First, the traffic update is sporadic. For much of any long journey, the normal green 'traffic info' is 'greyed' out and not being udated. Indeed sometimes, the symbol doesn't come on at all. I used to have a gizmo that picked up updates from the trafficmaster blue roadside posts which, while primitive, gave me instant data when I passed them. The is a step backwards.

Secondly, the system warns you not only of upcoming fixed gatsos but also tells you when you are in a mobile camera zone. That appears to include most of the main roads in Norfolk, with the result that it's sending you pinging warnings about this non-stop for minutes on end. I can't find any way if disabling this.

Thirdly, unlike my old Tom Tom, it DOESN'T give an audible warning when you exceed the speed limit, which is what I would like (or, if it does, I can't find how to do it). Call me old fashioned, but what I want to do is to keep within speed limits, not just to slow down to legal when there might be a camera about.

Garmin nuvi's are a very good brand. They have come a long way.
