As you might already know, the NanoMaps feature is available not only for the iPod nano but also for any kind of mobile device with a color-screen – especially for cellphones. To set the appropriate image-size the preferences for export allow you to set the width and height for the NanoMaps.

Images sizes for different displays
For all who do not know the resolution of their device I started a collection for common devices like the T610 on the left. You can find the list in the Library. If you did successfully export your directions onto any device that is not listed there, please leave me a note what device you are using and the resolution that fits best on its screen.



Image formats
TrailRunner exports the images as jpegs. Unfortunately not all cellphones can display them (like the K610i). Therefore you first need to convert the images to the png format. Heiko noted this and has sent screenshots of his Automator Action to easily convert the images :

- Select Files from Finder
- Change Image Format to PNG
- Change Finder Object Names


Image Transfer
In general I expect you to transfer the NanoMaps onto your cellphone using the Bluetooth File Exchange Application. Browse your device and drag the images into its pictures directory.

The new iPod models (nano and touch) have new screen resolutions. So I updated the Library for the new models. To change the export screen dimensions, go to Preferences > iPod and enter the values for your model there. BTW, one feature downgrade requested and build into TrailRunner 1.5 can also be set here: Disable the rotate NanoMap into direction of heading.

About NanoMaps
NanoMaps describe a route in a very compact and portable way to stay on track – without using an expensive GPS-Unit. NanoMaps depict every waypoint on your route with a snap-shot of the map-area around it. Additionally the map is rotated in a way that the direction you are coming from is always at the lower edge of the screen. The orange arrow then shows you the direction you should turn to. The biggest benefit is, that even if you did not put every possible track into your map you can still see that there are other tracks at a crossing.
Because it is not possible to have subfolders in the nano Photo-Library, green squares with a readable route-code in the overview mode help you to find the route you are looking for.
