Bob, the wife and I have been sick all week, so Garmin became low priority.
Overall the Garmin is very versatile. Thing is, it just depends on how you want to make it to where you want to get.
If you are on the road, want to find somewhere to get to. Obviously, you can get somewhere by scrolling back to the first page and enter "where To". When in GO TO, note the down arrow in the bottom right corner. This bottom right is a key to see all available choices.
Her favorite three to select are "address", "points of interest" and recently found.
Address is somewhat straightforward, but wait there"s more. Once saved, you can bypass the typing since it should become a recently found if you let the Garmin map it once, whether you go there or not. These become shortcuts for lack of a better term. Often the rear admiral will do all the locations prior to rolling a wheel. Then while in transit grab places quickly via recently found. It is recommended not to program your home address in case a Garmin is stolen.
If you enter "points of interst", this again is key to the lower right arrow to find a catagory. Once in a catagory, the Garmin will find locations from nearest to further away. Be very careful using this function, as it can take you miles of your route in the wrong direction. Imagine dropping a stone into a pond. The ripple goes in all directions.
These are the key screens to use.
With a Garmin, you can also upload routes and so forth. Every trekking Garmin I own so far, (have not tried the car or moto ones yet), but I beleive it is the same, uses a way to upload a route that limitis how many actual points can be loaded into the unit. So, lets say you plan a trip on your PC. There are many ways or programs to do this, Google Earth, Garmin Programs or even others. What heppens is that the route you dictate may have 2000 points for the Garmin to see. Unfortunately, Garmin screwed up, and limits uploads to 500 points max. If you try this and see the word Truncated, it means the unit analized your request, then gave you, without your input, what it thinks you wanted with the 500 point limit. Kind of like a Garmin Nanny.
The truncating may or may not be a problem. Jeanne and I also do a lot of off-road MTB riding. There have been many events we preloaded into a Garmin, on account of trucating, and the slower speeds, plus close proximity of one trail to another, the truncating reduuced what may have been 20 miles true to 5 miles Garmin as an example. There are ways around this, all time consuming and complicated. The easiest method though is plan shorter routes and tie them together. As an example, home to some hotel 200 miles away as one route, then the hotel to dinner 150 miles away, dinner to the next hotel and so forth. If possible, learn to save these as seperate routes you can call up. I beleive this would be under "custom routes" in the Zumo.
Consider also, how you setup your ride to get somewhere. There are choices such as shorest route, shortest time, tolls or no tolls etc. Garmins are good, but can mess with your head sometimes. If your unit has traffic avoidance, be careful with it also. Beore driving all over to avoid a wreck, ensure the time saved is worth the effort. As we have found out, avoiding one wreck via the Garmin traffic took us on a reroute, all was good until a second wreck, stopped everything.
Learn to zoom out and in on the screen whie rolling. This can be a huge help to see a general idea of your bearings.
FWIW, the Garmin manuals are worth maybe 15% of what the unit is capable of. It takes some practice, playing around and just trying stuff to see what you prefer.
Our greatest two Garmin adventures were
#1, a 175 mile MTB race we did on our Tandem MTB. All day and all night, self supported. 24 hours and a few minutes, all navigated via the Garmin which was preset with many routes on account of truncation.
#2 was Ireland last summer with my wifes parents. I was to cheap to buy maps from Garmin. AT bottom of the 9th, I was finlly able to get free maps into two units (one trekking, one automotive) of Ireland. Got to the Irish rental car place, we had resereved a car with a Garmin, but found out none were available. So I stepped outside and fired up both Garmins. Luckily both worked like a champ on free maps. So I learned to drive an SUV on the wrong side of the car and wrong side of the road. THe Garmins only error, my fault. I not onl loaded both units with road maps, but also trails at my wifes request. Headed to Mlarney Castle, driving along in the SUV, the Garmin has me turn off the paved road, down a driveway and wants me to go down a trail throught the bushes. We turned around, it recalculated and we drove in on the paved road.
All the best, sorry for the long post.
