I came across some great TomTom hacks this weekend, including one for aerial photos (or any kind of raster imagery). I haven’t tried any of these out, so you’re kind of on your own here. As always, I’d do a full backup of the unit before trying them. Regardless, these look like some great resources for the TomTom enthusiast:
TomTom ONE 125 review

UPDATE: This model has been discontinued. For a list of current TomTom models and their features, please see our TomTom comparison chart.
The TomTom ONE 125 turned out to be one of this year’s Black Friday stars. Aggressively priced, the ONE 125 is identical to the TomTom ONE 130, except that it only includes maps of the U.S., and not Canada too (as found on the 130).
Navigon 7200T review

NOTE: Navigon has pulled out of the U.S. market and we are no longer recommending their receivers. Check out our auto GPS buyers guide for our current recommendations.
The Navigon 7200T updates the Navigon 7100, adding 3-D buildings and a new interface. The 4.3″ wide screen navigator comes loaded with maps of the U.S. and Canada, and has text-to-speech, so you’ll hear “in one mile, turn right onto Maple Street” instead of just “in one mile, turn right.” Other features include Bluetooth for hands-free cell phone use, lifetime traffic, voice destination entry, Reality View Pro, Lane Assist Pro, Zagat® ratings and reviews, Exit Guide and DirectHelp. Whew; this thing is loaded! But the question is, how well does it do all that? I’ll dig into those features in more detail shortly. First, let’s look at how it compares to other units in the Navigon family.
Garmin nuvi 765T review
Hands on with the Garmin nuvi 765T
UPDATE: This model has been discontinued. For current recommendations, please refer to our auto GPS buyers guide.
The Garmin nüvi 765T is a member of the second-generation nuvi 700 series family, adding lane assist, 3-D buildings and lifetime NAVTEQ traffic to an already significant feature set. The 765T has a 4.3″ wide touch-screen, pre-loaded maps of the U.S. and Canada, stereo Bluetooth and text-to-speech, so you”ll hear “drive one-half mile, then turn left on Oak Street.” instead of just “drive one-half mile, then turn left.”
TomTom XL 330 review
UPDATE: This model has been discontinued. For a list of current TomTom models and their features, please see our TomTom comparison chart.
The TomTom XL 330 updates the TomTom ONE XL with a new design that includes a built-in mount, dubbed the EasyPortTM, that stows on the back of the device. Other than the form factor and re-designed speaker though, this new entry level model is almost identical to its older sibling.
Garmin nuvi 265T review

UPDATE: The nuvi 2×5 series has been officially discontinued. For current recommendations, see our auto GPS buyers guide.
The Garmin nüvi 265T is one of the second-generation nuvi 2×5 series models; I dubbed the first generation the “best entry level GPS on the market.” This newer series offers more mid-line features though — in addition to everything that made the original so popular, the 265T adds lifetime traffic and Bluetooth for hands-free cell phone use. It includes pre-loaded maps of the U.S. and Canada, has a 3.5″ wide touch-screen and comes with text-to-speech, so you’ll hear “drive one-half mile, then turn left on Oak Street,” rather than just “drive one-half mile, then turn left.”
Garmin nuvi 550 review

The Garmin nuvi 550 represents Garmin’s foray into the “crossover” GPS market, aiming for a device that functions well whether used for driving, hiking, cycling or boating.
UPDATE: Here’s a post I did about dual-use GPS, and how well they work for both road and trail. read more
Magellan RoadMate 1400 review
The Magellan RoadMate 1400 is Magellan’s new entry-level 4.3″ navigator. As a low-end unit, it only has 1.3 million POIs, and it comes without text-to-speech, so you’ll just hear “approaching right turn,” instead of “approaching right turn, Maple Street.” The 1400 does come with pre-loaded maps of the entire U.S.
Garmin nuvi 275T review
UPDATE: The nuvi 2×5 series has been officially discontinued. For current recommendations, see our auto GPS buyers guide.
UPDATE 2: The latest trans-Atlantic navigators to be introduced are the Garmin nuvi 2475LT and nuvi 2370LT.
UPDATE 3: The latest trans-Atlantic navigators to be introduced are the Garmin nuvi 2475LT and nuvi 2370LT.
The Garmin nüvi 275T is a 3.5″ touch-screen navigator designed to appeal to trans-Atlantic travelers, with pre-loaded maps of the U.S., Canada and Europe. It is one of the second-generation nuvi 2×5 series models; I dubbed the first generation the “best entry level GPS on the market.”
Magellan Maestro 4200 review
The Magellan Maestro 4200 is a fairly basic 4.3" navigator. It includes pre-loaded maps of the entire U.S., except Alaska. But as a low-end unit, it has only 1.3 million POIs, and it comes without text-to-speech, so you'll just hear "approaching right turn," instead of "approaching right turn, Maple Street."
