I’m a fan of the Garmin brand of GPS. I’ve tested out Tom Tom & Magellan but neither had the visually appealing interface of the Garmin, nor were they as easy-to-use. Prior to the 1390T, I was using the 875T. Both models are basically the same except the 1390T has some updated graphics and is slimmer. A good change Garmin made was to allow the power cable to plug directly into the GPS unit itself, rather than through the suction cup mount. The most important improvement is that the 1390T is much faster; it’s faster at locating the satellite signal (which is HUGE–the 875T can be painfully slow and sometimes doesn’t get a signal until you’re halfway to your destination!) and it has a faster processor so touchscreen commands are much quicker.
I do wish that Garmin would make voice command a standard feature on all their GPS’. It would also be nice if a zipcode option was offered, for those times that you don’t know the exact name of the city.
One change that Garmin definitely needs to implement is alternate routes, as in, offering multiple ways of getting somewhere.
Overall though, it’s a great product for the price and has definitely improved my quality of driving life!
