Installed to my Nexus5 and the installation was very smooth.
Also functions smooth and fine in all respects so far and nice to have such a high res screen, I only wish my eyes were better
One strange behaviour found when using a topo map (Friluftskartan Pro v4). All adaptions in TYP file does not show in StreePilot in the same way as it does in GPSMAP60CSx and Nuvis.
I have found the same effect once before a few years ago when using an Edge800 gps. Polylines does not respond to TYP info the way it should, i.e. contour lines and some roads will be drawn much to thick and in "wrong" colurs.

The workaround is to change the polyline to a bitmap in TypViewer also for solid, continous lines. Like railroads, power lines etc.
In this way you can get single pixel hair thin contours if you wish. Why it works this way I have no idea about but as long as it works I am more than satisfyed.
