I'm the original owner of an F900BT. By reading some of these threads, I'm thinking I'm not running the latest firmware. 

Current: 

Map Version: 2.000400

Version: 3.020100

There are mentions of running the firmware from later model series, as well. Is this possible? Any issues or advantages?

Based on other comments, it sounds like some of the update links are broken. 

Truth is, I generally like the functionality, except the touch screen sensitivity which got a little better after the update I did in 2009, but has still been really lame for a modern device. 

So, can I update and should I update, and if so, how?

Thanks!
