Great Model....READ MANUAL BEFORE YOU OPERATE
I map for a living so this unit makes sense.
I was worried about buying this model when I first read many reviews on this site as well as other sites carrying the Navigon 5100. The price however was too luring at 178$. I am pleased to find that the 5100 works great if you follow the recommendations in the manual.
I am a GIS analyst so i do have experience with maps and creating products similar to google earth. I will say that the Navigon is a great model for a intermediate user. I bought my mom a garmin unit because she will not take the time to read the manual nor does she care about extra funtions like optimum route, excluding tolls or 3d view.
First issue I read about was battery failing.
If you charge your unit for 6 hours (as recommended) when you initially buy your unit you will not have issues with your battery or recharge.
As stated in the manual, powering on takes a while. This is kind of a drag and i'd say one of my "cons" for the model. Powering on and off takes 7-10 seconds.
Many people complained about the unit rerouting with U-turns. This is something that you can turn off so they obviously didn't read the manual.
Rerouting is fast and includes traffic in calculation. Something Garmin does not do. You can also select what kind of vehichle you are in (bicycle, truck, motercycle, car) to add another factor to avg speed and rate calculations.
One of the best features for me and others i work with is the log funtion. If you need to log milage for tax purposes this is a great function. Or if you need to track workers to see if they go home during lunch or leave their car idle for hours this is great as well. With rising gas prices our company saved over 10,000$ due to this tracking.
The GUI is easy to understand if you go through the manual although not as "smooth" and fast as the Garmin unit.
Poi's are outstanding tons of symbology and even better if you get the freshmaps update.It's on sale through amazon for 56$ for 3 years. Totally worth it.
One thing you won't find in the garmin unit is an info button that tells info about the POI as well as a phone #.
All roads come from Navteq or Tele-atlas which is where Garmin gets their roads from. So complaints about roads being different on a Garmin doesn't make sense.
I do like garmin's POI loader. Very nice if you have work data that you need to add to your unit.
I haven't played with the navigon's POI's I suspect if you follow format and add through notepad then your only restriction would be the size of your card.
I must warn it's probably more advanced and not as user friendly as Garmin's POI loader.

* The best gps i have used so far ...
I paid over $1000 on a megallan gps that did not tell you the street name to turn down it was slow to get a gps signal , recalulations were
beyond slow and it did not have traffic alerts. I paid a faction of that price for this unit and its amazing. Turn it on and with in seconds it has a signal . It can tell if you did not make a turn in a split second and recalulates the new route before you even realize it . It tells you what street to turn down so you dont have to wonder was that the right street to turn on , and it has traffic alerts . I love this unit. I even purchased one for my spouse and one for my sister.

POOR INSTRUCTIONS
i LIKE THIS PRODUCT VERY MUCH. MY ONLY COMPLAINT IS THAT THE INSTRUCTIONS FOR USING IT ARE VAGUE, ONCE YOU FIGURE IT OUT IT'S PRETTY EASY TO USE, BUT MORE DETAILED INSTRUCTIONS FOR SETTING IT UP WOULD HAVE HELPED A LOT

* I purchased it for the mount! Nice unit! ...
Just kidding I got it for the navigation capabilities; however, the windshield mount looks like it was modeled after the alien spacecraft from the blockbuster War of the Worlds movie- so cool!
I've been a GPS user since 2000 when I first rented a car with a GPS system. Since then I've used various GPS software and hardware on Window CE devices and most recently on an AT&T 8525 PDA phone. I switched to a dedicated GPS since trying to run GPS navigation software on a phone gets complicated when calls start coming in.
Quality- Built well, thin, probably couldn't hold up to drops or abuse but overall it's a nice unit. Did I mention the mount? Absolutely beautiful design/concept. It securely holds the 5100 very well
GPS Reception- Folks have complained that this unit takes a long time to acquire satellites. I haven't experienced this. Typically time to acquire 5 to 7 satellites is approx 30 seconds to 1:30. Please in mind that acquiring satellites can be hampered by building (sky scrapers), cloudy days, positioning of the unit on the window (i.e. GPS units need clear visibility of the sky to receive good reception), heavy rain/snow and time of day/rotation of the earth. Overall no complaints; it performs very well.
Interface- For me the interface was very close to one version of software I had a while back on a Windows CE PDA. It does take time to learn the interface so don't think of this as an ATM or self-checkout lane at the store. Read the manual. Overall it works and I can find POIs or enter in addresses with ease. Doesn't seem sluggish to me. Only downfall is that I cannot sync my outlook contacts to it. Several settings are available in this unit for customization.
Screen- A tad bit washed out but not bad. You can still see the POIs, streets, etc. when driving. For the cost it's reasonable. You can adjust the screen brightness. There is a night time mode.
Navigation- The "Optimal" routing setting works best for me. It calculates routes driver would typically take. I've tested this and it works very well. Re-calculating routes works very quickly for me. Calculating a long drive, such as from Portland, OR to Dallas, TX does take some time to calculate but given the distance covered, I'm happy it can do it!
Text to Speech/Volume- The voice quality is good. A female's voice is used. She prompts me well in advance of the street name and direction. The volume when maxxed out is adequate but it's not going to over power your car radio or beat the howling wind @ 55 mph. Typically when I'm going some place I don't know I roll the windows up and turn down the radio. I pay attention.
Versatility- being able to swap between cars is ideal.
Traffic Reception- Stellar! This unit prompts me with traffic condition warnings. There is no subscription for this service as it taps into the local radio stations that broadcast this service.
I was really concerned about the negative reviews on this unit, but overall I'm satisfied and my friends consider me the "return king." Looking forward to many drives and not getting lost.
Cheers,
Brian
