right that's what it's all about...

regarding the precision of any GPS or navi, around this days... you may can put the following wisdom in context to it.. taken out of "Terry Pratchett's HOGFATHER" in hope he don't mind mention it here on HUMM...
it's all about believe and reality... make up your mind regarding the GPS units...

now the hype is like this:
---------
Susan: “All right, I’m not stupid. You’re saying humans need … fantasies to make life bearable.”
Death: “No. Humans need fantasy to be human. To be the place where the falling angel meets the rising ape.
Susan: “But Tooth fairies? Hogfathers?”
Death: Yes. As practice. You have to start out learning to believe the little lies.
Susan: “So we can believe the big ones?”
Death: “Yes. Justice. Mercy. Duty. That sort of thing.”
Susan: “They’re not the same at all!”
Death: “Take the universe and grind it down to the finest powder and sieve it through with the finest sieve and then show me one atom of justice, one molecule of mercy. And yet you act as if there were some sort of rightness in the universe by which it may be judged.”
Susan: “Yes. But people have got to believe that or what’s the point—”
Death: “My point exactly.”
---------

so do you believe in the precision of a commercial device ?
you may end up wrong or in the ditch some where if you do, but believe is the engine that keeps the human world spinning around...

hope this will help you to get over the misery you discovered with your new Garmin...

I can get home by navigating to my nearest city, from there I Know my way home
The sad thing is all the other databases know my home, all I have to do is type in the address. The garmin wont allow me to type in the address because half way through it decides to give me a choice of three wrong options. Using the correct way point for here will be translated to a house seven miles away the other side of my nearest city.
On playing with it today, and it also does not seem to know of the existence of the city of St Jean pied de port. It does know about a village near it though.. I really need to keep my old Michelin maps in order to find places near to where I want to go that garmin knows about.
I am not trying to test it to its limits, just want to be able to use the HOME feature, and was trying to plan a trip into the Spanish pyrenees which will take me through St Jean on to Auritz in Spain and then along the foothills. This is a really nice ride I have planned for May. I may yet buy some real maps, not sure what I can use the garmin for.. maybe a paperweight?
Update.. It also can't find several small towns which are marked on my michelin maps. It can't even find Pussy, so how useless is that?

Are you sure you re running on the City Navigator® NT map and not the basemap?


My version of City Navigator finds Saint Jean Pied de Port but it has to be written " Saint-Jean-Pied-de-Port". I have only tested it in mapsource not with the GPS.

Thanks, yes, it will find it if , and only if, I type exactly this "Saint-Jean-pied-de-port"
which is not how it is spelt normally
I would have expected, correction I was sure it would find it from just "st jean" and onwards, it does some others but not that one.
I am going to have fun locating Mont st michel, or is that Mont-st-michel or mont-saint-michel or le mont st michel or le-mont-saint-michel?

well lets go back to your 1st post...
by now I realised that you have a NUVI 765T type of in car "electronic map box" and not a real GPS navigator unit right ?

now if I got that right in the end... you may stuck with the build in software for now, I'm not familiar with the NUVI range, so my question is:

is your NUVI 765T able to load the external city navigator-NT software ?
how many individual waypoints can you store ?
how many of your own waypoints can be used to build up a route ?

my 60Cx can store up to 1000 if I remember it right and mainly using this database for targeting navigation in 50 routes.
any unknown coordinates can be found in a separate database that's depending on the additional software you have to pay for separately.
the build in world map don't know any address database at all, at least in my case so I had to buy the miniSD chip to make use of the "auto-routing" option and a better resolution on the screen.

I know the cheap TomTom box a bit and there is a expensive option to upload add-on software for all sort of needs from over the net... but still this fancy "road-nav" boxes are not a very advanced navigator as we know it from the "old days"... yes they are electronic map-boxes meant to replace the big bulky paper books.... no more no less...

depending what you are looking for... well you may have the wrong unit in the first place....

from the manual,

Maps & Memory:
Basemap:
yes
Preloaded maps:
yes
Ability to add maps:
yes
Built-in memory:
internal solid state

Accepts data cards:
SD™ card (not included)
Waypoints/favorites/locations:
1000
Routes:
10

Question, what size and speed sd card is good for it.


it also has
nüvi 765T
Preloaded City Navigator® NT for Europe (full coverage)
Lifetime traffic¹
FM traffic receiver with vehicle power cable

latest 2010 maps.


My purpose was to have help passing around and through major connurbations preferably by not using the Peages (toll roads). I can do most of most journeys easily from maps, but it can get a bit hectic in strange cities. Also if I go wrong in a city, I had hoped the recalculate would eventually get me back on trackto my destination.

OK than...
regarding the manual you should be fine at least concerning the additional maps !
dono about the speed for the card, but any should be ok, as long you look out for the storage size of it, which the unit can cope with... (my 60Cx can take up to 8GB, the miniSD containing the NT-2010 maps only needs 1.8GB and the pre loaded maps on this miniSD cards is 2GB only, just to have some additional space to fit some tracks too)

your purpose seams reasonable to me... to make live a bit more comfortable that's OK...

so.. dose the unit has this City navigation-NT 2010 already installed, or did you just read that of the box ?
in case the unit is equipped with a miniSD you may only got a 1GB card in it or less, with no maps at all, in that case you are running on the world basemap I presume...
in case you got the city navigator-NT 2010 DVD sold with the unit you have to buy a empty miniSD card and transfer all the maps to the unit with the sd card placed in to it, or use a SD reader if you got the miniSD adapter card that got the size of a std SD card.

Now just to let you know... the process of transferring all European maps to a 2GB miniSD last some 12 hours ! one reason why I bought the Garmin miniSD with the pre loaded maps in the end and not the DVD !

Well you where on about that you would like all maps like the European and eastern maps on your unit... well in that case you have to buy either both pre loaded miniSD and swoop them as you go, or you have to get both DVDs install them and transfer all maps to the unit at ones. because all maps will be stored as "one" file to the miniSD, the mapsource program is recompiling the lot together and sending it to the card.

check out what is installed in the unit, there must be a point in the menu that is showing you what maps are active and you may find out that way what part is missing that coursing you headache...

I use an older GPS but I think that on a GPS with preloaded maps you have to activate the maps (via Internet) before you can use them. It has something to do with Garmis free upgrade of maps within a few months.

I have it connected to my computer. The internal memory is about 4GB of which 2.5GB is used. This is the streetmaps for the UK and most of western Europe. but I am finding An unacceptable percentage of errors and omissions including spelling errors. Spelling errors are very bad because it cannot then find until you have figured out by continually trying different combinations for it to recognise a place. For instance I tried for over quarter of an hour to find St Jean pied de port. I have since found my home. It has misspelled the name by adding an S as the third letter wheras in fact there is no S in the name. Ie name is listed as nasme. Not helpful nor conducive to putting ANY trust it it whatsoever even when it appears to be working.
