UPDATE It turns out it isn't OVI MAps, but the App manager who is downloading several megabytes!

I have several maps preloaded (cities folder = 1.8GB), including the maps for the location where I am. When start maps in offline mode, it works (with the GPS locked using Location Test).

Today, I started it while on GPRS, and OVI Maps at startup said 'Downloading Data' and proceeded with downloading 5+ MB. I hadn't even asked it for anything yet, not even routing.

WTF?

If the maps are pre-loaded, why the hell is Maps downloading more stuff?
Has anybody else seen this too?

And can anybody tell me how to prevent this? Dataplans here in Belgium are pretty limited AND expensive....
