Hey kv12. I have my unit and everything works great except for my navi. Now the SD card it came with has the iGo maps and everything on it I assume but the navi screen is just grey with a white cross-hair. If you could give me some advice it would be awesome or even if you wanted to help me out in person would be great too. Thanks in advance and reply to me thru email at jeremy.luis.quintela@gmail.com.
