have tried it and I think it might just work...
Before doing anything BACKUP YOUR SD CARD ! !
Then find the files Scan/Make/Asia/Acura inside there you will see a car.bmp and a
car_new.bmp file.
Rename the car to car_new
Rename the car_new to car
You will have to do this for each vehicle you have software for....
Restart your scanner and see if you have the dealer logos. If it doesn't work. Just
reformat and install your backup.
If you update your software, you will probably have to do it again each time you
update..
Tell me if it works for you ?
