4410 problems

I have been using my 4410 for about a month now, but I have started realising some real problems with the GPS.

Apart from sending me in the wrong directions sometimes, I am really annoyed by it's Outlook Contact integration. I find that the addresses in my contacts list through Outlook are generally not acceptable and/or non-existent by the 4410's point of view!!

I am really getting peeved with this glitch in the system, anyone else got this problem??

I can not believe that at least half of my contacts list is unheard of!!
