This modification will replace the red arrow used in 2D navigation mode with an image of your choosing (car or anything else you want to use).
Required Software/Files/Content
- Copy of DATA.ZIP
- Image to use as arrow (the higher resolution the better)
- Photoshop (or other image editing tool capable of color channels)
Step 1: Prepare the data file
Unzip your DATA.ZIP file, and navigate to:
DATA/pioneer_ui/common/
There you'll find a daycar.bmp and nightcar.bmp. Rename these to something else (daycar.bmp.bak and nightcar.bmp.bak work well) so you can go back later if you want. Now we're ready to create our new images.
Step 2: Create the images
Open the image you want to use as your new arrow in the image editor of your choice (we'll be using Photoshop CS2 here). You need to select just the car so that the background can be cut out.

There are a number of ways to do this, I won't go into detail here, but the best way to get a clean selection is with the pen tool. With the car selected, invert the selection and remove the background so only the car remains. Retain the selection.

With the car still selected, switch to the channels palette and add a new channel. It will automatically be created as an Alpha channel, and filled with black.

Now select #cacaca as your foreground color, and fill the selection. This will create a mask of the content we want to show up on the screen, the car.

Next you can trim the image, resize the canvas so that it is a square, and then resize everything to 82px X 85px. Also, make sure your car is facing forward (up), so it displays correctly on the map.

Now we can save the new image into our DATA file in preparation for installation. Select Save from the file menu, and in the dialogue that pops up, make sure you have your file type set to BMP, and that Alpha channels is checked. Browse to find DATA/pioneer_ui/common on your computer and save the image as daycar.bmp. A dialogue will pop up asking you to confirm the image settings, just click OK. Complete the same process, but save the image as nightcar.bmp and you're ready to load it on your F-Series.

Step 3: Load your changes
Go back to the DATA folder you created in step 1 above, and select all of the subfolders and the two files. Create an archive of those (right click -> send to -> compressed file). You will end up with a new zip file that you will need to rename to DATA.ZIP.

Boot your F-Series into Windows CE using the TESTMODE hack and copy your new DATA.ZIP file to the flash drive. When the copy is done, remove your SD card, and restart the headunit to get your new car to show up.

That's all there is, enjoy your newly customized nav system!
