theres no data to be lost really unless you already have manually put maps on there...i did that witd it worked ... i had the same error msg you guys had too

decided to do it manually, find instructions here:
http://handphone-solution.blogspot.c...0-without.html

ignore the instructions regarding symbian ovi maps. just download the zip files for the countries you need, and then extract them somewhere and copy them in the MyDocs/cities/diskcache folder.

What I don't get is why Nokia make it so complicated in the first place.

Why don't they just have an option in Ovi Maps itself to just "pre-cache region" and show a list of areas you can download - right there on your phone. Even smartphones should do that, bearing in mind they are telling us the N900 is more a computer than a phone, why should we need to use ANOTHER computer to do it? (although the unofficial method we could do directly on the N900 I suppose)

Typical that I spent hours at this two days ago But let's hope it works now, although it seems that some of you still have problems?

To those of you that lost map-data, remember to back up the cities folder manually first. Better safe than sorry

Written from my new and shining N900, a stunning device!

tried it, keeps telling me that device is connected in connected in mass storage mode and there is no luck of it detecting in pc suite mode!!

I moved the qf file too via terminal

do I have to install pc suite for it work ??

OS: Windows 7 x64 - many people here claim it works fine on this OS

what am I doing wronng?

thanks in advance
cheers
Jackie

no luck on Vista 64 - any one here have success?

I saw the instruction from nokia website, but it does'nt work for me. Map loader can't detect the n900 on either pc suite mode or mass storage mode.

like adancau said back up if you already have maps on there already

it should work on windows 7 as long as you RUN-it in WinXP compatibility mode

tried that as well, still nothing!!
