I was on cdaleparts.com and they are selling the Optimum Diagnostic & Maintenance Kit for $300.00, but they are selling the Optimum Map Select Kit for $875.00. Now I know with the D&M Kit you use your computer to change from map to map and that the Map Select Kit is used for changing between like 3 different maps while riding. If I got the Map Select Kit would I have to buy the D&M Kit to load the maps, or does the Map Select Kit have the D&M Kit with it.

Thanks,
Chance Mayfield
