SOURCE: unocking Garmin SD maps
it is in the box it came with, on the back of the instruction book.
If you did not buy it 'new in the box', you will have to refer to the 'activation' code sent to you email.
The Garmin Nuvi 760 does not require SD card maps if you are using it in the US, btw...

I dont thinki the 330 handles 4Gb SD cards I think 2Gb is the maximum that is why it isd taking so long and runds out of space so cannot properly load the maps.

Take a look at the Garmin support page - there is a Question " Why do I get a not enough space message on my Nuvi2xx when trying to update my mapping?"
It tells you how to remove the unused voice files to free up space.
I have a Nuvi 255WT and deleting the voice files alone was not enough, so I set about removing a lot of other stuff *** NOTE THAT IF YOU FOLLOW WHAT I DID, DO IT AT YOUR OWN RISK **** it worked for me but there is always the risk of deleting a file that the device needs.
Also I was stupid and didn't try and save the files to a directory on my MAC before deleting them, from the satnav - worth a try so that if you can do that you have a chance of recovering one that you delete if you want it back.
First I also removed the un-needed text files - leaving only the 3 British-English files
Then I removed all of the POI files that were clearly examples/samples
Then I removed all of the Vehicle files except the one I was using
Then I removed all of the large ExtData files - now that was the one that caused me the most worry as I wasn't certain what they were there for!
This gave me a bit over 140Mbyte of free space which was enough to install the 2010 update for all of Europe.
Now I don't know whether the C510 has the same amount/less/more memory than the 255WT - so this may or may not work for you.
I didn't have an SD card available, which is why I went this far. I am going to get one and see if I can find out how to load the maps onto that.
cheers - Jeremy
