Upgrade to 8 stupid question

[red rocket]

just upgraded again this time to 8 .I did it to 7 last year unlocked every thing ok as I've done it again now .

Now this is the silly question bit do I have to remove the loaded maps from my cards & reload with the version 8.I know that must sound a rediculous question bur I'm deadly serious

No, just have the v8 selected on Mapsource and transfer to the GPS - it'll update everything

do I have to remove the loaded maps from my cards & reload with the version 8.

Yes.

Just reload. When reloading all old maps will disappear.

Surely it will only load new routes in 8 from the pc to the unit but if out & about & i need to make up a route it will have the old maps on the card which are surely out of date thats why I was asking if I need to uninstall & load 8 to my cards hope this makes sense Ian

when you download any v.8 map/s to the gps it will wipe all existing maps from the unit.

routes stay put, but i dare say any routes in the gps unit created in v.7 will not work without a recalculation as the maps differ.

I can only answer from my own experience. When I upgraded from v6 European City Select to v8 City Navigator Europe, it overwrote the v6 ECS map yes and the speed camera overlay I had downloaded but personalvroutes I had already saved remained on the GPS (unless I am greatly mistaken).
The crux of it is you don't have to remove anything from the unit in answer to your original question !

Right!

He is asking two questions;

1. No, you do not have to uninstall the old version

2. Yes, you do have to reload the v8 maps to the GPS

 

[red rocket]

Oh well rightly or wrongly I thought I'd uninstall so I knew which areas to reload as I didn't think I would see which maps I'd originally downloaded in the first place & be able to duplicate them exactly if that makes sense.

Just hope any routes I have will still be ok but don't suppose it'll take too long to re due them..

You guys have no idea how lucky you are to understand all this stuff.

You have two different groups of data involved here.

The first, User Data, consists mainly of WAYPOINTS and ROUTES. These you create yourself. The easy way is to create them in MapSource on the PC but you can also create them in the unit. You can send this data from the PC to the unit or vice versa. Note - if you want to have your own saved database of routes these must be saved on the PC! Typically you may have hundreds of routes & waypoints saved on the PC but you only upload some of them to the unit when you plan to use then. The unit stores this data in its internal memory. Not on the data card. Uploaded routes & waypoints are always added to those already in the unit.

The second, Map Data, consists of MAPS and POINTS-OF-INTEREST. These comes on a DVD from Garmin. You can buy a new version every year if you want. Some GPS models comes with this data preloaded but the normal procedure is to (in MapSource on the PC) select the geographical regions of interest and then upload these map data to the unit. This information is stored on the data card. Uploaded maps always replaces all maps on the card.

Hope this info helps to understand the general concepts...

 

[Doughboy]

Beautifully explained and spot on !

Uploaded maps always replaces all maps on the card.

HMR has provided an excellent explanation of the concepts, however, there is one tiny exception to the above statement that folks should be aware of. I only mention it to avoid possible confusion in the future.

If your GPSR stores uploaded maps on a data chip, CF card, or internal hard drive, and does NOT come with preloaded maps, then HMR's statement is 100% correct. Whenever you upload a new set of map segments, the previous set is erased.

However, if you have one of the newer models of Garmin GPSRs that came preloaded with maps - in other words, one of the units that you simply take out of the box and start using, no fooling around with MapSource and the computer needed - then you have the possibility (but not the obligation) of having two different sets of maps loaded in it. One set will be the 'preload' that came with the GPSR, and the second set will be any map segments from a different cartographic product (e.g. Topo, BlueChart, home-made maps) that you have uploaded to the residual memory of the GPSR.

In this case, things work like this: The maps that are preloaded by Garmin when the GPSR is made reside in a protected area of memory, and, generally speaking, can only be over-written if you are updating those maps with a newer version, using a Garmin DVD. This includes, for example, updating CN Europe version 7 to version 8 by using the Garmin updater DVD and hooking your GPSR up to your computer.

The 'user maps' are not protected in the same way, and you can freely upload new map segments anytime you want. When you do this, you over-write the user map segments that were there before.

It's a minor point, and only applicable to GPSRs that come with the maps preloaded.

Right!

I avoided this issue to make the explanation short. Maybe I shouldn't have. What complicates the story is that there are exeptions also to this exception. (there are units that comes with preloaded maps that are not protected....)

 

[red rocket]

Well thanks for the very well explained information guys .

I like the bit where if you download the maps it wipes out the others so supposing this .

I have 985 mb loaded on my card in the unit & I wished to load all of Italy which I dont have room for so decide to leave off say the top of Germany to make room for it are you saying I simply pick the new maps wanted missing out top of Germany then including Italy I simply send the new 985mb or there abouts worth to the unit & it will automatically remove northern Germany or where ever I miss out when making up my next gb worth.

Likie I say

Red Rocket:

I think you have the general idea now. Just be aware that the CF cards (or Garmin data chips) need about 5% free space for overhead. In other words, if you have a 1 gig CF card, in real life you should not plan to load much more than about 950 megs of data onto it.

The worst that can happen if you select too much data for a storage card is that you will get a warning from your computer that the card can't hold everything you selected. This can be a bit of a nuisance if you have been waiting 40 minutes for a slow computer to finish loading a card.

Last question honest .Are you saying any routes I have stored on my PC ie.Austria Switzerland previous trips if reloaded to the unit for our hols again they will automatically work on v8 or do I need to re do them on the new version8 on the pc first & delete all old routes

So if it says data loaded successfully all should be ok or at least something like that definately never said any thing untoward & when mimimizing the maps on the unit it shows all the little gold squares

...Are you saying any routes I have stored on my PC i.e. Austria, Switzerland, previous trips if reloaded to the unit for our hols again they will automatically work on v8 or do I need to re do them on the new version8 on the pc first & delete all old routes

The routes that you created using previous versions of the same cartographic product (e.g. a route created with CN 7) will work just fine after you upload CN 8 to your GPSR. When you activate the old route, you will get a message to the effect of: "The route you have chosen was created with an older map version. Do you want to recalculate it?" If you answer yes, the route will be recalculated and you will be presented with a route that is substantially the same as what you had before.

If you think about it for a moment, the requirement to recalculate the route cannot be avoided, because some of the streets may have changed from one version to the next of the map. If a new roundabout was built somewhere along the way, the GPSR will have to recalculate the route to provide you with guidance through that roundabout.

For practical purposes (going from one place to the other via either the fastest or shortest route), these recalculations are transparent to the user and will not change your route very much, if at all. If, however, you have established a route called 'My Favourite Twisties', and you want to be sure that you follow that route EXACTLY, it's best to load the old route onto the new cartography on your computer, recalculate it there, inspect it to make sure it is to your liking, then save it (with the new cartography visible on the computer screen) and then re-download it to your GPSR. Because the route was saved on the computer with the new cartography visible, you will not be presented with any recalculation requests when you activate it on your GPSR.

FWIW, I have routes that I created 8 or 9 years ago with Roads & Recreation version 1 (back when the only roads listed were the ones the Romans built) that recalculate and work just fine on CN 7 or 8. So, not to worry.

Thanks again Michael as always it's a pleasure reading explanations from you & others who actually know what your talking about.
Hopefully one or two others gained from my queeries unless I'm the only real numpty
