Offline navigation: I have Navigon on it, installed a few days ago. Works well with an Eastern European map that I use. Can't go to the house number, just to the street, but it may be user error, since I'm more familiar with iGo and Google.
The volume cannot be changed, it's either maximum or mute, but not in between.
An Italian guy (peppino44255) modified it to work with the Asteroid's wheel and Next/Prev buttons.
It works, but when I really have to go to a new place, I'd mount the standalone on the windshield or even use my smartphone. Waze would be more useful on the Asteroid.
I'll see if I can find the download link for you.
: see below.
OK, I got it from here
. The page is in French.
What the page, and the comments, say:
1. Get the program from here
(on the page, fill the CAPTCHA, then press the button under it, with the text "Valider et telecharger le fichier" on it) or from Rapidshare
. It's a 120 MB RAR and downloads slowly (was at 40-160 kbps for me, took ages).
2. Get a Navigon map for your country. I don't have sources for this. The page has a link to France's 2010 map, but newer Navigon maps work, too. I tested it with a 2011 map. I found the map I need from one of the links in the comments there.
3. Get an SD card that you will use in your Asteroid, if you don't have one yet. For now, access the card with your computer, using a card reader or by other means. Make sure it is FAT32 formatted. FAT16 (classic FAT) would probably work, too. Create a folder on it, called "Navigon". Actually, you can put the program in any folder, even in the SD card's root, but this is how I did it.
4. Unpack the RAR you downloaded at step 1, into this folder on the card. If we'd call the card "SD", you would now have:
5. Copy the *.map files (US.map, maybe?) that you got at step 2, to SD/Navigon/map/.
6. Unmount the SD card from your computer and put it in the Asteroid.
7. On the Asteroid, go to the Install menu. You will see "Navigon" in the list. Install it.
The main Navigon menu, right after you start the program (the third photo
on the French page), is navigable with the Asteroid wheel and the Asteroid Next/Prev buttons. In most text boxes (e.g. when inputting a street's name), you can press the big round Parrot button and the Asteroid keyboard will come up. Changing between uppercase/lowercase/numbers is by pressing the menu button. Changing between night/day is through menu button->Day/Night, when a map is displayed.
The comments say Navigon will default to the system's language. I have the UK firmware and Navigon's menus are UK English. US will probably give you US, not that there are many differences.
Just for making it clear: you will have to leave the SD card inside the Asteroid, otherwise the navigation won't work.
If you know how to create a startup config file for Navigon, please do tell. I'm especially interested in setting the volume, since it's at maximum. The Asteroid's many volume settings do not affect it. What I did, is go to Navigon's settings menu and mute it. I did not try an external USB keyboard, maybe one can use the horizontal arrow keys to adjust the volume slider.
Got a wireless mini keyboard for it, from eBay, this one
. It cost 18.82$, free shipping. It works - input is much easier and faster, and I can also set Navigon's volume. It's not backlit, but for the money, it works.
