At first glance reviewing GPS units may not sound like a hot rodding topic. But in my case I am specifically using the GPS unit to replace the mechanical speedometer in my Sedan Delivery. And I have a sneaky suspicion a lot of other rodders are going to discover and utilize the GPS speedometer function in the near future and use these units in place of normal speedometers. They are a lot less hassle than getting a mechanical unit installed and they are a lot less expensive than an electrical or digital speedo. Also, many now claim that GPS provides more accurate speedometer readings than any mechanical or electrical unit on the market.
So my review:
First...my giant error. When I bought the first GPS for my rod I figured all units were pretty much the same. And since there are basically only two manufacturers (TomTom and Garmin) and they cost about the same, my thinking was they were pretty much interchangeable. Boy was I wrong.
A couple years ago I bought my wife a Garmin (she uses it a good deal for her work) and she has been very happy with it. Worked like a charm right out of the box. We plugged it in. Turned it on. And within moments it had located the necessary satellites and was ready to go.
So I figured, since the TomTom was the same price and had the same basic features, it would provide the same ease of use. And when I found one on sale at Amazon.Com, I ordered it up. Big mistake. I should have done my homework and done some web searching to read up on user reviews
Right out of the box there was trouble. I plugged the unit in as directed...and nothing. It powered up okay, but couldn't find a single satellite. And it needs FOUR to operate properly. It would just churn and churn away with the message "Searching for Satellite".
So I went on line and started reading. First off, the TomTom web site does, apparently, recognize they have a problem with satellite connectivity because they offer a free software download which is supposed to correct the problem. So I went through the process, loaded the software into my unit, and with wild anticipation went out to plug it into the car. But just as before, the unit failed to find the necessary satellites to operate.
So I went back on line and read even more. And come to find out, mine was not the only unit to exhibit this failure to operate. A large number of TomTom owners reported the exact same problem, sometimes the problem was sporadic and sometimes folks could never get their units to pick up the signals they needed.
Exasperated, I went out and bought a Garmin. Brought it home. Plugged it in. And just as in my wife's case, the unit operated flawlessly from the get-go, picking up the necessary satellite signals and providing an easy to read speedometer (as well as destination navigation as needed).
One other feature which I really like about the Garmin is that it has an automatic shut down. When you turn the car's ignition off the Garmin senses that and pops up a screen asking if you want to keep the unit on (using its built in battery power) or if you want to turn the unit off. If you do not choose either alternative, the unit automatically shuts itself off after 25 seconds, thus saving it's battery.
The TomTom unit does not do this. When you turn off the ignition, the unit automatically switches to battery power. And if you don't remember to turn it off manually, it will remain on until it exhausts it's battery (usually about 4 hours). Now maybe their is some software choice where you can correct this default setting, but I was unable to find any way to do that.
So a big thumbs up for the Garmin and a big thumbs down for the TomTom. And make no mistake, there IS a difference between the two.
