I actually could not decide between the Garmin Nuvi 255w or the 750 model, so I decided to buy them both for comparison. I mounted them both to my car windshield and gave them various addresses to find together. I found that both models took the same routes and announced upcoming turns and street names at practically the same time. One thing I noticed about the 255w was that it was updating my position on the road more often, I'd say about 3 times as often as the 750. This made for smoother graphics on the 255w of the vehicle moving along displayed roads, where the 750's display was more of a "jerky" movement. I also found that the display on the 255w was a bit brighter, clearer, and more vivid than on the 750 in both daylight and at night. Another feature I like on the 255w is the graphic turn indicator in the upper left corner, which the 750 lacks. This is a small arrow which shows upcoming turns and the distance to that turn. It also show things like a fork in the road, (ie: a Y intersection), and which fork you will be taking. The 750 just displays text on the top line for upcoming turns without the arrow. It's just a little extra feature on the 255w which I happened to really like. The 255 also automatically adjusts the font size of displayed text so that even lengthy text will fit.
Another feature on the 255w is a display of the posted speed limit on the road which you are currently on right above your current displayed speed. I found myself not even looking at my car speedometer as I could easily see my current speed and the speed limit of my route at a glance. The 750 doesn't have this feature. I also like how they moved the zoom in (+) and zoom out (-) buttons on the 255w to the same side of the screen which makes it a bit easier. On the 750 the zoom buttons are on opposite sides of the screen.
Now there are some features on the 750 that the 255w does not have. The 750 can broadcast it's sound over your FM radio with the supplied cigarette lighter cable, and it has a headphone jack, which I found to be nice features. The 750 also has an MP3 player and an Audio-book player, which the 255w does not. Another really nice feature of the 750 is the car locater. This is a great feature if you are parking in a really big lot, such as at an amusement park or a fair. The 750 marks your location when you remove it from the car, then you take it with you and it remembers where you parked and takes you right back to your car. The 255w doesn't have the car locater.
I also thought the the voice prompts of the 750 where more pleasant sounding than the 255w's. The 750 sounds more like a real female voice, where the 255w sounds more robotic.
Another thing to consider was that I paid $50 less for the 750 and it came with the FM transmitter cable and a USB cord to connect it to your computer for updates and downloads.
My final decision was to keep the 255w and return the 750 because I really liked the graphic turn indicator and the posted speed limit and current speed indicators. I didn't find a need for the 750's MP3 player and Audio book player, but that is up to personal preference. Since the USB cable was not included with the 255w, I purchased it on this site for $10. I also intend to purchase the MSN direct cable when it is available in August 2008.

This is my first automobile GPS, and I did a lot of research before settling on the Garmin 780. I live in the Washington DC Metro area, so all of the extra features work here. Upon its arrival, I downloaded and installed the latest Garmin WebUpdater v.2.41 and then updated my 780 from software version 2.50 to 2.90. I also updated the Bluetooth and other firmware, along with the languages that I use. This all worked flawlessly in a Windows XP virtual machine on a Linux host. FWIW, the 780 will charge off of the supplied USB cable.
The 780 acquired the necessary satellites in just a few minutes when first activated, and does so in less than a minute for subsequent activations. I found the screen brightness to be fine for both day and night. I'm using the 780 with the Garmin Portable Friction Mount. Smashing windows and stealing GPS devices is the sport of choice in the DC Metro area, so I wanted no evidence of a GPS extant when I left the car. The friction mount works perfectly on my Honda Accord dashboard and stores easily in the center console, leaving no trace of a GPS behind. Very cool. The 780 easily fits in a shirt pocket, so it's not necessary to leave it in the car.
I tested the 780 immediately by driving during rush hour to a residence across the river in a tangle of park roads off of the beaten track, then returning at night. The Garmin had no trouble creating a very fast route to the destination that bypassed most of the heavy traffic during rush hour. On my return, I bypassed a turn on its preferred routing. It recalculated a new route in less than a second which was the exact right answer. The new route wasn't a recapture of the original route, which wasn't possible from that location, but an entirely new route. The routes it picked were appropriate for the times of day traveled, which can be a daunting task here if you don't know which roads go which direction during the appropriate rush hour. DC is a notoriously difficult area to navigate, but so far the Garmin seems up to the challenge.
I found the volume of the internal speaker to be more than adequate even with the radio, air conditioning, and windshield wipers going. Voice notifications led upcoming turns by an adequate amount, and the voice prompts always helped me get into the correct lanes in plenty of time for upcoming turns. During a particularly tricky section where several major roads converge on a bridge, then diverge on the other side, the Garmin gave almost constant appropriate guidance to ensure that I took the correct forks and turns. I was quite impressed.
The Bluetooth paired quickly with my Motorola Razr V3. It even provided its PIN code at the appropriate time. The phone functions work great and it's easy to hear over the 780 speaker. The party on the other side of the phone said that I sounded like I was in a tunnel, which is typical for remote devices for autos. I have another BT hands-free device and it garnered the same comments. The Garmin's on-screen phone cues make hands-free easy.
Activation of the MSN Direct service was simple over the Net. On initial activation of your free 3 month trial, they offer a 6-month extension for $9.95 which gets you to 9 months of service total for less than $10--a very good deal. MSN Direct information took a while to load the initial information, but then it said that in the Quick Start pamphlet. Once loaded, the traffic, weather, and news worked great. Gas prices were behind by several days, which is an eternity these days. My favorite (and cheapest) station wasn't listed.
Overall, I'm very happy with the 780. I'll be working it out heavily in the coming weeks, including on a road trip to another city with MSN Direct service. I can't believe that I waited this long to take the plunge to a GPS device for my car. Even though I'm a master with maps, the Garmin suggested a clever routing that I did not previously discover on my own. From what I've seen so far, the 780 will be a highly valued addition to my road warrior kit bag. I can recommend the 780 without reservation.
