How do I configure my 7 wire system for the Nest Thermostat

[ASP]

Hello to all. I’m super excited about installing my new nest thermostat but however the compatibility checker is stating that my 7 wire system isn’t compatible. I’ve read posts where some users have had luck wiring their 7 wire system. Could someone please assist me so that I done  waste too much time. I appreciate you all’s help in advance. 

Thanks

Here’s the configuration:

W - white wire

Y- yellow wire

G - green wire

O - orange wire

R - red wire

B - brown wire

C - blue wire

Can you post a picture of the current thermostat wiring?

What is the manufacturer and model number of your HVAC system?
