I recently bought a MW600 from Sony Ericsson, it's a great device but it doesn't seem to work so well with the N900. I read the topics from maemo.org trying to make a sense out of the incompatibility but the N900 seems to react totally random. I can't say that every "working pattern" from the other users that posted "how to's" worked every time. And it's sad that with any other Sony Ericsson phone the MW600 works flawless. Syncing with the device it displays the hour, the song that's playing, the name of the person who's calling and not just the number etc. If anyone found a solution please share it. I bet a lot of people would be glad.
