Quite a lot inside mine!
I plugged my sat-nav into my pc via its usb lead and the sat-nav is displayed much like any usb storage device.
Apologies for the poor quality pics but for some reason the sat-nav screen flared like mad on the camera unless I turned the brightness very low.
With the sat-nav plugged into your pc/laptop open explorer and you should see something like this.
The file highlighted red is the one we’re interested in.
Open it up with notepad or any other text editor and you will see something like this.
My satnav is an RAC 4300 WIDE model but many other models are listed in this file so I guess this will work on many models.
The setting HasShell is what we’re interested in.
When I initially opened it up this setting was HasShell=0
I changed it to HasShell=1 and rebooted the satnav.
On reboot all the following was revealed.
Before changing the shell setting only the map function was available, now I have a music player, a video player, an fm function that sends the
satnavs audio to my car radio, and even a windows desktop!
In the image below we can see the familiar windows red cross that usually closes a window This wasn’t there before I changed the shell setting. If I
click that I drop into the windows desktop and all the stuff we see above.
This particular satnav has a socket for a memory card so now whenever I’m taking grandson on long journeys I fill the memory card with movies, then
I hang the sat nav on the rear of the passenger seat, and the sound comes out of the car speakers. He loves it.
Its even possible to have the satnav giving voice directions while a movie or music is playing.
The desktop is windows ce and theres plenty of apps to be found on the web.
Inspecting some of the other files I found a lot of empty or partially written functions. I’m not sure whether the software was still being written
or whether it had been edited so that it complied with the laws of the country where it was sold, for example I found a half complete function for
television, television is illegal in the front of the car in the uk; so I’m thinking it was deliberately disabled by removing some of the code.
Depending on where you are located you may find more or less features.
Who says hacking doesn’t pay!
