Help Setting Up New 2460 from Old 1490, Please

There is really no need to use the SD card for storing maps on the 2460. Your 1490 had only 2GB of internal storage, which wasn't enough to allow for the full installation of City Navigator NA and the larger JCV file. Because of this lack of storage space you needed to delete files and eventually needed the SD card to hold the large JCV file and even some, or all of the maps.

Your 2460 will have at least 4GB of internal storage and since you have already deleted all un-needed files, you'll have plenty of space for your map files on the unit.

To copy your favorites to the new unit, copy the current.gpx file from your 1490 to your computer. Then rename the copied file to temp.gpx and place it in the GPX folder on the 2460. Boot the new Nuvi and your favorites will be created on it.

I'd like to use the SD card instead, to leave room to accomodate the ever increasingly large map updates. With this first out of the box map update, I have 4.54 GB used, 2.76 GB free.

We are all free to configure our PND as we feel is necessary but to confirm what t923347 advised I want to add that in the 2460 there is no need to delete anything to accommodate the map, you are free to use the 16 GB SD card but just so you know the US or Canadian government have no plans of expanding their territory in the foreseeable future, remember the 2.76 GB free you now have is more than your 1490 ever had.

I agree with t923347 & flaco of not needing to use an sd card on the 2460 since there is plenty of room for expansion, but as stated the choice is yours.

If you do intend to put additional maps on the SD card, you will need to create a folder on the card named "Map", exactly as written with capital M.
You can then place the map in that folder and give it any name you want as long as it has the .img extension at the end of the name. You can add as many maps as the SD card can hold but will slow down the boot process to read them.

When I buy a new unit I ALWAYS make a backup before doing anything with the unit, in addition I make an additional backup whenever I make changes to the unit.

As t923347 described how to copy your favorites from your 1490 I would suggest you delete the temp.gpx file from the gpx folder AFTER the 2460 is rebooted and the new favorites added.
The reason being is the current .gpx file always recreates itself on every boot. Should you do a hard reset (recommended after firmware/software updates) then the favorites from your backup file (temp.gpx) will be loaded again. This is why some people may wonder why they can't delete some favorites and they always reappear after a reboot after deleting.

Another tip on the 2460.
On older units you HAD to put POI's in the POI folder for Nuvi to recognize. On the 2460 you can put them anywhere on the unit or on an SD card and the 2460 will recognize them as long as they have a.gpi extension.

Flaco, Good point re the free memory comparison. However, I have seen posts on POI Factory that even Garmin says the map files are growing in size to a point of critical mass.

I'm not so sure about your point about territorial expansion. I hear Lord Stanley and the Canadians are hopping mad at Los Angeles.

muell9k, A very helpful post, thanks. I did a back up before tinkering (though I will admit I didn't do a backup before deleting the unwanted language files. Oddly, the map update put some of them back).

To be clear, what is a "hard reset" on the 2460? Holding down the power button for 10-12 seconds or so until it cycles back on?

I thought I read on POI Factory that the increase in boot time for SD-loaded maps was minimal.

As to your last paragraph, do you recommend putting the POI file on the SD card instead of internal memory? Are POI searches/access noticeably slower for being on the SD card?

Yes but, the map updates increase by MB not GB so historically 2.76GB of free space will last for longer than the Nuvi will. I believe that amount of free space is more than the total space required for the whole City Navigator Europe map file, which is much bigger than the CN North America.

I have the majority of my POI's on the Nuvi, they don't take up much space.I see no difference in speed having them on Nuvi or SD card.

I do find having certain POI files on an SD card a benefit. For example I have a POI file that has audio alerts for Police Hiding Points, they mostly appear on highways at turnaround points that Police use.
Sometimes they are a big nuisance since in most cases there are no Police there. If I don't want to hear them I simply eject the SD card.
I suppose I could cretae a new file without the .wav file but the unit will still display them on approach.

P.S. You can always use WebUpdater to recover all the language files for your original backup. Then copy them from your Nuvi to the backup.
I don't think that's necessary though since you can always recover them from WebUpdater

One thing I cannot get over that Garmin has not implemented is separate audio options for voice navigation versus all other sounds. It seems so 20th Century to require an all or none approach to sounds. I would like to hear speed camera and speed trap alerts along a route being navigated without having to hear turn by turn audio. To do that I have to end the current route and not mute the volume. I'm no software or hardware engineer, but it can't be that hard to have options on the audio settings page besides one volume for all or one mute for all.

On my 1490 I have a very loud gong sound for RLC. I can reduce the volumne on the unit and still hear the warning. I use this one.

Hey ... my 2460LMT has 8(eight) GB of internal storage ... plenty of room for future expansion. My old 1460LMT had a scant 2 GB of memory.

I can not think of any reason to use an SD card ... which are slower to access than the internal memory.

I'm a bit confused by the reports that some folks say the 2460LMT has 4 gb of storage.

I keep POIs with audio warnings that I really only need on trips (certain kinds of shops and museums). I pop out the card when I don't want to hear about those trip POIs.

I noticed on my 2555 that I could set different volumes for different items. Wish the 2460 did that.
