You should consider putting space on the board for a built-in GPS. Trimple and 
others have absolutely tiny GPS receivers these days that draw barely any 
power. I just purchased 12 channel Trimle Lassen IQ receiver for $60 from 
www.sparkfun.com. The GPS is slightly bigger than a quarter and draws 
somewhere around 30mA @ 3.3 volts.

A full power tracker that is just one physical piece of hardware would be 
pretty hot. Literally connect GPS and 2 meter antennas, and power. Done.

 I just finished installing yet another Kenwood TM-D700A and have an external 
GPS does take room, draw power, and make more hassle.
