Hey guys, glad you're enjoying Primo so far
Sorry I saw this a bit late, but better late than never right?
First off, What kiltman says is true, in iGO you will see the route name mentioning the first and the last waypoints. A tip many users on our forum use when making a route is to name the first waypoint and the last point with relevant information. For example: The first waypoint is named "Stratford" and the last one "200miles". We make our routes mainly in "Tyre" which is software that has a free version and is also compatible with Garmin, TomTom but also iGO:

Also right about the tips regarding the saving of a route. When you first load a .KML route from \CONTENT\USERDATA\ROUTE\ you should go back into Route Options, More, Save Route. This is because Primo seems to load slower with .kml files in that folder. The more you have, the slower the initial loading of Primo (only the startup). By saving it, it creates a .dat file in your profile (\SAVE\Profiles\01\routes) which doesnt affect the loading time, plus has the added bonus of giving your route a name you like. I myself move the .kml files after saving them to a different folder on my GPS to be able to share them later if I need to.
Now on to the voice files. It's a shame I started reading this AFTER just sending a private message to Phil but I might aswell post it here too
You can edit the voice files by messing around in the command files that are within the voice.zip files. This is however very time consuming and risky if things don't turn out too well. The standard voice files, that end with -lua.zip, are also not that easy to modify. There are also voices that use different command files, so called ".csv files". Those are easier to read, and thus easier to modify. To make it even easier, I found a German forum where someone made a program to edit those .csv voices without even extracting the voice .zip files!
Long story short: you need different voice files than the ones you have by default in your iGO installation. Go to CONTENT\VOICE\ and delete (or move them somewhere on your pc as backup) the English (US) voice files.

Those are the same (US) voices you had before plus two new ones: Dave, Jason, Amy and Kenneth. Open the English_Voices_iGO.zip and put all the .zip files inside in \CONTENT\VOICE
Now for the voice commands editing.

Extract the contents to a folder on your pc. Open CommandsEdit.exe, select File > Open and open one of the voice files you downloaded earlier. Edit all the distances you want

Oh before I forget, version 1.9 of the Motorcycle Edition is out. I made a special version for the forums here which already includes the voices mentioned above AND has a new loading screen for the 4,3inch units (like the Rage):

This also includes two new route calculations: Scenic and Less Freeways. If you already have an earlier version you don't need to extract the SAVE folder from that zip.
