It's been tricky but I've finally got it. You need to edit the .bat file and in the file you will see that it says deviceemulator.exe. First you need to download Microsoft Device Emulator and install it on your computer. Then go to the .bat file and in front of "deviceemulator.exe" you need to type the location of that file. For example: "C:/program files/microsoft device emulator/1.0/deviceemulator.exe" That is most likely where it will be installed. And make sure to include quotation marks. Then, there is another part in that .bat file that refers to a folder that Boris gave us the download link for called avic_80. You need to type another file location for that one as well. This is what mine looks like: C:/Users/Brian/4pda_avic/avic_80. Then just save the .bat file and double click it to make it run. When you do, it will open up WinCE and you can click on My Flash Disk >> APL2 >> iGo >> ezrider.exe
That will start up the emulator for you. Just put the map file you want in the map folder and put the language file you want in the lang folder and you will be good to go.
