Garmin or TomTom

I guess I was an early adopter of satellite navigation. Over ten years ago I had a navigation package from TomTom (or Palmtop as they were then called) installed on my Psion 5mx and through a complicated series of cables hooked it up to a Garmin eTrex and powered the whole thing in the car. It wasn’t bad, but it was a bit clunky, had no voice instructions, took an age to recalculate if you went off route, and had a number of mapping errors – Micheldever Station was marked on a railway bridge half a mile from the station for example.

From there I progressed onto stand alone units, sticking with Garmin as my handheld GPS units were Garmin’s and could share desktop software and maps. Currently I’m running a Garmin Nuvi with full maps of both Europe and North America and an FM traffic receiver, and that has served us fine.

Last week it turned out that both Beth and myself needed the satnav as both of us were going to be going to unfamiliar places. Obviously we didn’t need a second satnav, but since my iPhone has a nice little GPS on it I thought I’d take a look at the options. Conveniently PCPro have just done a group test of satnav applications, and TomTom came out top of the pile. Since one of my biggest bugbears with the Garmin Nuvi is the fact that the FM traffic often reports traffic jams when it’s too late to avoid them and I’d heard good things about the TomTom Live Traffic service I thought I’d go for the TomTom application despite it being one of the premium priced satnav products in the app store.

First off, it is a nice little app, slightly confusing to navigate around until you get used to it, but fine on the road. The Live Traffic service is impressive, and indicated traffic pretty consistently, and the routing based on actual road speeds certainly allowed it to pick routes which matched much more closely with short cuts I knew about rather than the more obvious routes the Garmin would take.

However there is a really big problem, even ten years later, there are still problems with the TomTom maps. Whilst Micheldever Station is now in the right place, other things aren’t. For example a local petrol station whilst close to the right spot is the wrong side of a road junction, speed limits are wrong, and whereas my Garmin will guide me right to my front door, even saying on which side of the street it is the TomTom app can only manage to get me to the street.

There are more serious problems too. We live adjacent to a military base, and whilst there are roads that go across, they are closed with security guards on the gates – the TomTom map doesn’t reflect this. The map is also just plain wrong in places, a major example being around the Atrium in Camberley.

Below are three screenshots from my iPhone. The left hand one is from the Maps application showing an up to date satellite picture of Southern Road down the side of the Atrium. The second shot is from TomTom, the only app of the three that costs any money. The third is from Waze, the community navigation app that is a free download.

Looking at it you’ll see that the TomTom version is very inaccurate. It incorrectly shows Southern Road running all the way to Southwell Park Road, and running all the way to the A30 at the other end – it doesn’t. Instead it is blocked at both ends with an access road a short way down. There is also an entire roundabout missing which in the TomTom version is replaced by a pair of junctions. Whilst the Atrium is pretty new, it’s been built for a number of years, and the road layout TomTom has doesn’t bear much relation to what is there now, nor to what was removed when the Atrium was built. The third screen shot shows the layout according to Waze which is correct, and the layout is also correct on my Garmin Nuvi.

It is fair to say I’m not impressed. TomTom, much like Waze has the ability to report map errors, but with Waze I’m not paying a premium price. Garmin have up to date maps, is it too much to expect that TomTom could do the same? Suffice to say my experience with TomTom is not going to have me switching. Whilst I am impressed with the Live Traffic it is pretty fundamental to have accurate maps, having found a number of errors locally where I know the area, how can I have the confidence travelling in a strange area that the TomTom is correct?
