I wanted a GM 1/2 ton pickup with an 8 ft bed.  Only light pickup sold that way is the work truck.  Fine.  Don't need anything fancy.  Don't need no 4 door pickup. 

The GPS screen is so small.  Is it possible to buy some other screen?  I could build a wooden box to hold it in and fasten it to the dash just in front of the current screen.  

My problem is knowing what screen to buy and how to wire it.  

Who could help me with this in Nebraska ? 

Or is my idea just crazy ?  lol.
