How to update Maps in Nuvi 350?

Hi,

I have a Nuvi 350 with NT9 Europe maps, and I've just bought and installed on my PC City Navigator NT 10.

When I select all the maps to update to my Nuvi, it tells me I only have 220MB left, and need ca. 1.4GB.

Do I need to get the old maps off the Nuvi first, and if so, how?

Thanks for any pointers...

Does the 350 have an SD Card slot? If so you might have to send the maps to the SD Card and keep them there.

It does have an SD slot, but I don't have a spare card and don't really want to have to buy one.

Using Map Source, I grouped the UK maps into a .gdb file, and the Spain maps also. I uploaded the Spain maps, then the UK maps, but the Nuvi only shows the following to be present:
City Navigator Europe NT 2008 [1] UK
City Navigator Europe NT v9

Both are ticked, so how do I know which UK maps the Nuvi is using? Also, where's the Spain maps?

Before I bought the Map upgrade, I thought it would be a simple case of replacing the maps already on the Nuvi. Seems that's not to be...

OK,

Having done some more reading (now I know what I should have been searching for), I have a simple question.

Can I delete the 1.3GB garmin/gmapprom.img file from the device and just have garmin/gmapsupp.img? (Or rename the new gmapsupp.img to gmapprom.img?)

Don't know about the problems you are having loading your new maps, but would advise that you backup up your map files before deleting anything, just so that you have something to restore if it all goes tits up.

Well that's Censored

the unit then!

It says loading maps, then runs a green progress bar across the screen, and jams on 90%.

It won't even register as a USB device with my PC so I can't copy the old file back....

Help please - I need this unit in a few weeks time to drive abroad with...

__spc__ - yes, I was a bit afraid of something like that happening. And I tend to forget that taking a backup isn't necessarily foolproof if you lose the PC connectivity - I've nearly been caught out by this, as some others have too.

I think you will have to go to Garmin as suggested as it's almost certainly corrupted now - is it new enough for you to go back to the retailer, who might also know enough to recover your unit? Is it under warranty (assuming it's still valid)?

But another (much less likely) possibility is trying to get into the unit's software in some way. Does anyone still recall the discussions on these forums of the various "press-screen-area/turn on/reset" type of combinations which give access to various Garmin mangement screens? Do they know of any such command which might help here?

Hooray - it works!

I had left the SD Card in the unit, which had a smaller set of the new Europe maps (so as to fit on the 1GB card).

Removing that, the unit now starts as it should and recognizes the new maps being installed.

So, in short, to update the new NT10/2008 maps on the Nuvi 350:

1. Attach Nuvi to PC, then MOVE the /garmin/gmapprom.img map file from the Nuvi to the PC (as a backup).
2. Using Map Source, select all the map regions, rename the map set as appropriate, then send to device.
3. When the process is complete (ca. 2hrs), rename the new ca. 1.3GB /garmin/gmapsupp.img to /garmin/gmapprom.img.
4. Disconnect & restart the unit.

Worked fro me, and 4 simple steps.

SO WHY DOESN'T GARMIN TELL YOU DO THIS AFTER YOU UNLOCK YOUR NEW MAPS??!!

Thanks for all help offered, my unit's working again!

__spc__ - Before you changed your file names, you said that with just UK & Spain loaded the unit routed you between the two ok. I would be interested to know if, now, it will still successfully route you between two countries through an unloaded/unchecked country. I feel it won't but would like to know for future reference on my Garmin.

Many thanks.

@BigPerk

I no longer have the UK/Spain map set - but I am tempted to create one and upload it; even simpler, create a new mapset from two separate and small map sections!
So, I can't answer your query, but I will try one day soon. Just not before I need my Nuvi for holiday duties!
