Pros Usual Garmin quality and easy to use interface
Cons A bit pricey; traffic receiver not very useful in my location
Summary My 3rd Garmin automotive unit (nuvi 350 > 650 > 770). the only reasonI got the 770 was that I plan to be in Europe this Fall, and wanted the included European maps.
My biggest complaint (or maybe just a quibble) with the 770 - and probably the entire 700 series - is that the routing algorithm occasionally brings up really weird routes. If one ignores directions that one knows are not optimal (speed or distance) and goes on far enough to force a recalculation, usually the time to arrival drops significantly, indicating the original route was not optimal. What is worrisome is that if one is not familiar with the area one is travelling in, suggested routes might be sub-optimal without one knowing. Yes, in the end you will get there, but the point is to get there in the shortest time, or the shortest distance.
The new features; track logging, last stopped location, are nice to have, although the latter was easy to simulate. Nicer yet is the automatic switch to map display after some distance of travel, rather than hanging at the previous screen for ever.
Finally, my comments on the included traffic receiver. Admittedly, I am in an area just west of Toronto, Canada, where there is no coverage. However, I do drive into the Toronto area enough to a)test this feature, and b)evaluate it.
So far, I have found it basically useless. The availability times for Toronto are limited. Worse, there seems to be a signifificant lag between what is happening on the ground, and what is being reported. usually by the time I get to a reported problem it has disapeared. I doubt if I will renew the servie after the trial subsciption expires.
Finally, my consisten complaint with Navteq maps, which are not really Garmin's problem (although TomTom at leasthas managed to deal with construction road closures and incorrect one-way instructions). Navteq maps are usually at least one year, and often at least two years out of date from what is actually on the ground, in fast-growing areas. Where I live, I all too often find myself driving across open fields! Garming ought to work with Navteq to come up with a faster up-date cycle, and at lower cost than is presently happening. After all, if I can go out and buy a printed map for maybe $20, why should I have to pay more than 3 times that for an electronic map on media that costs less. Someone in the electronic mapping business is taking serious profit.
Pros nice interface. Have coordinate option
Cons Routing misleading.
Summary With routing option of ?Shortest Time?, Nuvi 770 frequently suggests routes that exit from highway to narrow local roads. The drives are more winding and take a lot longer.
My guess is that its routing is based on speed limit of each section. The problem is - when some sections have no speed limit, Nuvi770 assumes highway speed which is shown on GPS.
It happened many times in US. The worst time it happened was when we travelled in Europe. We tried to drive from Interlaken, Switzerland to Zurich Airport. There are highways linking the two destinations, as shown in google map. Nuvi770 suggested a route of local roads and inside cities.
Nuvi770 is not a reliable GPS. It can get you to destination eventually. But many times, it took you a lot of longer in winding roads. Hopefully it can be improved. My Nuvi770 has software version 4.9, the newest.
I have good experience with Magellen which I rented in Europe. It has much optimal routing. The problem is that it does not have coordinate option to find destinations.
Pros 1. It works ok 2. It has some nice features 3. Nice creen 4. Light weight
Cons acquisition time - poor
The maps-too old
area OTHER than metropolitan regions- not up to date
software often "recalculates"
system picks odd routes
reroutes are simply ridiculous
TTS must be reset often
Support i- scant + disappointing
Summary Quite honestly, NOT worth the price. I was a Garmin follower, but I have seen the light. MUCH cheaper units actually do a far better job (eg, Navigon, TomTom, and others). At Garmin they think they invented navigation and that they still own the roads, but that is soon to change. In reality, sorry, but the stink!

Pros Nice sleek
Cons This unit have lots of problems with the bluetooth , it freezing trying to enable the blutooth , I had two replacements from Gramin and still have the same problem. Web updater will not solve the problem
Summary After one week of using this equipment , it reset itself for no reason, then I was unable to pair my phone with the Bluetooth , unit kept freezing , I contacted Garmin support, they have tried all they can by updating the software with no success, the unit was returned to workshop , a replacement was received , I experience the same problem again , I am not the only one as I have found that several people have the same problem on the internet. Now Garmin will not reply to my Email .. I am stuck with this unit !! I have two other Garmin units 660 & Etrex venture, I had no problem with thm
