Testing Notes: This review was written using a production, retail boxed version. Garmin's WebUpdater was run to bring the software up to the current version as of this writing, version 3.40.
The unit was testing over several days of real-world driving, both on highways as well as back roads.

Figure 2: What's In The Box
Garmin's nuvi 1490T ships with the following items in the box:
Figure 3: Garmin nuvi 1490T, Front
Physically, the 1490T looks almost identical to the 1390T, just a little bigger thanks to the 1490T's 5-inch display. The 4.3-inch WQVGA (480 x 272 Pixels) color touchscreen display is framed by a casing constructed of matte and glossy black plastic.
Except for the power button located on the top of the device, there are no physical controls on the nuvi 1490T. All operations are performed via the touchscreen interface.
Figure 4: Garmin nuvi 1490T, Rear
A single speaker is located at the rear of the 1490T, as is the mini-USB connector. The USB connector is used both for power, and for connecting the nuvi to a PC/Mac.
Figure 5: Garmin nuvi 1490T, Side
The nuvi 1490T is about 35% thinner than previous Garmin nuvis, measuring about a half an inch thick.
A microSD card slot is located on the left side of the 1490T. Mapping data for the USA and Canada is pre-loaded on the internal memory, so you'll only need to use a microSD card if you want load additional maps or store lots of photos.
The 1490T has 2 GB of internal memory, of which approximately 140 MB is unused and available to store photos, routes, etc. Should you need more space than that (i.e. to store additional maps), a microSD card can be used for storage.

The power button is located on the top of the 1490T. Press this button to turn the device on or off.

Figure 8: Suction-Cup Mount and Cradle
The nuvi 1490 includes a suction-cup style windshield mount. The cradle (shown above on the right) snaps onto the tip of the mount (shown above, left), forming a ball and socket joint that can easily be rotated into the desired viewing angle.
Figure 9: Attaching the Cradle to the Mount
The cradle has a socket in the rear that snaps onto the tip of the suction cup mount. Connecting the cradle to the mount is simply a matter of pressing the cradle firmly onto the mount until the ball snaps into the socket.
Removing the cradle is equally easy: twist it to the right or left until it snaps off the mount.
Figure 10: nuvi 1490T, Docked
This ball-and-socket style mount is easy to use, holds up well against normal wear and tear, and keeps the GPS firmly in place while driving.
Figure 11: nuvi 1490T, Docked
Garmin's mounting hardware is excellent. The windshield mount holds the nuvi firmly in place and vibration-free when driving, even at highway speeds. It's easy to adjust the viewing angle with one hand, and without having to turn any knobs or slip any levers.
Figure 12: nuvi 1490T, Docked
One minor grievance with the nuvi 1490's mount: unlike the nuvi 7x5 windshield mounts, the 1490Ts' windshield mount isn't powered. That means you'll have to connect the 12v power cable to the GPS's mini-USB plug on the back of the device each time you take the 1490T in or out of the car.
Notice that the vehicle power cable has an integrated FM traffic receiver. The 1490T includes free (ad supported) lifetime traffic service, as indicated by the 'T' in the 1490T's model number.
Figure 13: Traffic Receiver, Explained
The included traffic receiver provides free, ad-based traffic information that doesn't require a subscription. The receiver is integrated into the power adapter, so you don't have to worry about connecting any additional wires or antennae to receive traffic data.
Figure 14: Adhesive Mounting Disc
An adhesive mounting disc is included for those looking to mount the nuvi 1490T on the dashboard rather than the windshield. I'm personally not a fan of this method, as it can be difficult to remove the mounting disc later without damaging your car.
FYI - a better option is to use a friction mount, as it's less permanent and can quickly be removed when leaving the car unattended.
Figure 15: USB Cable
A standard USB cable is included, and can be used to connect the nuvi 1490T to a PC or Mac, as well as charge the battery.
