I recently ended up purchasing a TomTom GO 2535M Live portable 5” widescreen GPS unit at a Best Buy store. With tax, the total price ended up being just under $300 dollars.

For the past 6 years or so, I’ve had a Garmin C550 with a 3.5” touch screen that is hard drive based. Since I drive a truck over-the-road, the Garmin has been running almost 24/7 for those six years, taking very high amounts of what can often be severe jolts and vibration along with occasional extreme heat and cold. I’ve paid to update the maps in the C550 about three times, but I’m reluctant to pay to update the maps again since I really don’t know how much useful life the hardware, particularly the unit’s hard drive, has left in it. For the time being, the aging Garmin is still working so I’m using it side-by-side with the new TomTom unit.

In my experience the perfect GPS unit has yet to be sold. Each brand has it’s strength and weaknesses. I’m including in this software-based solutions such as Google Navigation, Telenav, etc. that frequently comes bundled with Android or other smartphones. Maps used in GPS devices have improved dramatically, but they are accurate only about 90% of the time, and this includes Google itself. As a truck driver I’m looking for new addresses on average about two to three times a day, sometimes more and sometimes less. About 10% of the time I run into errors, sometimes with the potential to cause catastrophe – think narrow streets, weight-restricted bridges, etc.

Right after I bought the TomTom I had to go to a cold storage in Chicago, Illinois that the TomTom could not find, but the Garmin could. It turns out the street had been given two names with dual street signs, one below the other. The TomTom could find what was probably the original numbered street name, but not the other, which was a woman’s name the city was obviously trying to honor. At that point I was unhappy with the TomTom’s performance, but decided to continue to give it a longer chance before rushing into a knee-jerk judgment of the device or its software. The TomTom redeemed itself later that day by warning me around a 15-mile-long traffic backup in northern Indiana on I-65 which ended up saving me hours of sitting waiting for a major accident to be cleared and the road opened back up.

The TomTom is different than the Garmin. TomTom has a different way of doing things. The GO 2535M Live is a fairly sophisticated device. It even has a full-time GSM data connection to the TomTom server with the ability to do real-time Google searches, either locally or in other locations, get live traffic and weather updates, and do real-time rerouting to avoid traffic problems. Though the unit has free lifetime map updates from TomTom and a year’s worth of live “HD” traffic and weather updates, the live “HD” traffic and weather update service is just under $60 per year. Once you create an account at TomTom.Com you can sign in to your account with the unit itself. Incidentally, I’m willing to pay $60 dollars per year for accurate, up-to-the-minute traffic and weather information. That type of information can end up saving a lot of time and trouble as long as it’s presented as soon as it becomes available. The unit can even accurately display areas of traffic backups and slowdowns.

After I’d had the unit for about a week and a half, it was sitting on my dash and suddenly started going into a rebooting loop. Regardless of what I did, the unit would just keep rebooting. After a quick call to TomTom’s support number (I got right through to a live support person), they advised me to return the unit to Best Buy for an exchange since I was well within the 30-day exchange window. I’m pretty sure it must have been some sort of software/operating system error, since a few minutes before I had entered a new favorite location.

The replacement unit is working great. The TomTom rep gave me a reference number to call back with when I had the replacement unit so they could make the necessary changes to associate it with my existing account in their system, which I did.

There are much more expensive GPS units on the market (sold at truck stops) aimed specifically at truck drivers which look enticing, some of them priced up to 200% more than the units sold at a place like Best Buy or other big-box retailer. I talked to a driver that bought one of these very expensive trucker-specific GPS units. He said it was nice, but he didn’t feel the extra trucker-specific features were worth the substantially higher price he had to pay for the specialized unit.

It turns out feature I like the most so far is the ability to do Google searches in order to input destinations rather than go through the standard process. Other features I like are that that unit has enough room on its bright, high-resolution 5” widescreen to display my current speed, the current time with the time zone automatically updated, and speed limits with audible alerts if I’m going over the speed limit. It also has a lane assist feature which primarily warns if an upcoming exit is on the left or the right. Another useful, though not always consistent feature is that it can be set to announce upcoming points of interest such as rest areas and truck stops, along with virtually any other type of other business one can think of, including user-defined points of interest.

I am enjoying the TomTom GO 2535M Live. It’s not yet perfect, but with continued updates from the folks at TomTom I’m certain it can continue to improve.
