I have just finished installing Garmin XT (v5.00.50) into my Nokia N97 which is using S60v5.
I have not really try navigating with it yet. However, the software do not seems very stable on this device. GMXT has crashed twice (shut by itself) so far while testing.
Initial impression is that Garmin has made some addition of touch screen buttons in this v5.00.50 because the N97 is without the soft keys which most of the Nseries have (eg N95 8gb).
I have also tried loading in the earlier version of GMXT into the N97. GPSr can work but because of the lack of softkeys, i can't quit the program.
I tried both portrait mode and landscape mode on the N97. Both mode are usable.
In portrait mode, part of the road name display might be cut off. (See pics below)
In Landscape mode, the road name is displayed properly but the map will not utilise the phone full width.
I have taken some screen shot for clearer reference.
The start up page.

Navigating

Due to the program i used to take the screen shots, its unable to show pictures in landscape mode. The shots do not turn out as what i see on my N97 screen.
