I have a 2003 MDX and the dash display screen has gone haywire. It has navigation, which we never use, but it also is the A/C and radio control... does anyone know if I can replace that screen with a non-navigation screen? They are easier to find and significantly less expensive, and it looks like the Alpine part number (39810-s3v-a110-m1) is the same, and what I really need is the AC control...also, would a 2004 unit work? Again, it looks the same on the front, but the model number is a210 instead of a110. Any help is greatly appreciated!
