I found exactly the same thing, the unit has to be stationary for a while, you need to swizzle it 
around its vertical axis until you get the maximum signal strength, and then leave it for 10 mins to 
get a fix. It must not be touched or moved during that time.

It is pretty impractical for a mobile device though to do that.

Lets hope some of the techniques to preload data will help this.
