I bought this top of the line unit with after hearing some rave nuvi 680 comments and personal garmin gps reviews from colleagues, I work with a group of people to program global positioning system applications, so needless to say I have my fair share of experience to draw upon when I say this is the best their is out there right now. It is near perfect in many ways to the way I design and test applications of tracking, with my only upset being that it takes a tad bit longer (1-2 seconds) to recalculate routes when you stray from them as compared to some units I have been in contact with.
- The algorithms and programs of the tracking system work better then 99% of stuff i’ve seen, with the course estimation, timings, positions and recourse features being incredibly accurate when compared to similar priced gps systems meant for personalized usage.
- Hands free calling was especially great for me, recieving calls and becoming distracted and hazardous was a problem my girlfriend always gavbe me hell about.
- The interface is very clean, simple, navigatable and intuitive with me not yet having to use any sore of manuals or help guides to locate all the dozens of potential tools the garmin gps systems bring to the table, and the added and brand new tools of the nuvi 680 generation type of systems.
The additions of data added into your nuvi in real time and real world accuracy utilizing MSN direct service is a big plus over a street pilot system I previously owned, and to spare the readers attention span and my keyboard longevity, I won’t even began to write out all my positive feelings and experiences the added data can bring to the navigation experience.
All and all this was coming highly recommended and now I total see why, it simply rocks, and with the lowest prices on the nuvi 680 I’ve seen dropping from $1000+ to 600-800 lately, it is incredibly affordable and worthwhile for what you get, and expect to see many many new people discovering the true versatility, function and pure joy the 680 nuvi series from garmin brings to those whom come in contact with it
I first heard about garmin’s nuvi gps systems a long time ago on an article about science and economy, ever since then I have been interested in these units, and now that I have one, I must say that going back to life without one would really suck!
Happy Traveling!!!
