Maps

How often does Nokia update maps? Or how often should I down load a map to my phone?

I actually thought about this myself not long ago. I've had my 920 for about 2 months and have not had to do an update to the maps yet after updating them the day I got the phone. This is a guess here, but I'm going to say 3-4 times a year. My Garmin Nuvi which I use in the car has free lifetime maps. Garmin use Navteq (Nokia) for their maps. This gets 4 map updates per year (so a new map every 3 months). Whether the phones get the same cycle of updates per year, like I said I'm not sure, but I would say it would be similar.

I do believe the HERE maps now have incremental updates as well, so you don't download a whole map when updating. The updates will just add/remove roads, so the updates will be a much smaller size to download.

Oh I did not think that was possible I thought was like a giant picture and you would have to update the whole thing. But suppose it could be like a grid and you only replace the relevant ones.:smile:

Yeah it's quite clever really. Apparently it's due to Nokia introducing vector based maps on the phones. Here's an interesting blog post from Nokia about it.

So it not a photo at all but but all mathematical, that sounds very complicated indeed.
