Just what exactly did you all get?

 GS 2600 display $5000?

 Itc receiver $2500 (sf2 ready $4500)?

SF2 autotrac activation code($8000),sf1 autotrac activation code($3000)?

Universal autosteer ($3100)?

 To make a receiver sf2 ready you will need to get a COMAR number from dealer,and receiver serial number  then phone stellarsupport and input a 24 digit code.

 To make the display autotrac ready you will need a COMAR number(possibly the same one as above) phone stellarsupport with the challenge code from the display and serial number. Then input a 25 or 26 digit code

 Then if you want to use sf2 differential correction you need to give stellar support the receiver serial number and buy a sf2 subscription for 3 or 6 months ($400 or $600) or 1,2 or 3 years if you like ($800,$1400,$2000)
