Maestro 4040 hack
When I bought my refurb Maestro 4040 I had no idea that it was a Windows CE device that is hackable. I discovered this as I searched around for a way to unlock the voice command feature without forking out an additional $99.
You are able to turn the Maestro into a PDA rather easily. All of the information I used was found by reading this thread. When plugged into your computer with the included USB cable, the files on it become available as one big flash drive, making modification extremely simple.
As you can see in the included pictures I now have the ability to watch movies, play solitaire, listen to MP3’s and various other functions on top of using the included GPS functionality. The SD card slot comes in handy to load up movies or MP3’s. The final set up works very well albeit there are a few bugs. To complete the hack I basically had to rename one file and copy a couple directories and files over to the device. After doing so, the unit reboots and BAM, it’s hacked. Of course before tweaking with the unit I backed up everything to my local PC just in case things blew up. If you have a Maestro 4040, or another Maestro model, you can DL the files I used for the hack here. Of course there is no guarantee of your success. I don’t know if this will work on other Maestro models or not.
