I made changes exactly as instructed to. I changed the daycar and night car bmps in the common folder to daycar-bak and nightcar-bak. Then i added the bmp icon i wanted to use and renamed it daycar and nightcar. Rebooted and the arrow still shows up? Now im stumped because i beleive the arrow should no longer show up because its named daycar-bak and nightcar-bak. Can anybody tell me what i did wrong?
Why did you start a new thread on this? Posting this in the thread about this topic might get you more attention.

Follow Stephanie's diy on changing the arrow in 3D mode. Helped me out lots 
Bingo! Thanks for the thread. I followed her directions and was able to do it. I am still having one issue with it though. Maybe you can help me? I am attaching my bmp. It has a red background which i thought would go away when put on the system but it doesnt. How do i get the red background to go away?
Man I had some problems with that too and unfortunately there's no easy way to explain it, haha. I used photoshop cs3 to make a .bmp with an alpha layer. I'm not sure if you're familiar with it as I had to go through a little crash course to figure it out (at least I hope I did 
). Try and see if this works:
These may help. There on a smaller scale but I like them.
