There is no limit to the number of banks you can set up in illumiQUOTE. In the top right corner of your illumiQUOTE site is a settings link. Of course, you need to be logged in first. Assuming you’re logged in click settings and scroll down to the bank section. Choose your bank(s) from the drop downs and add more with the plus + button.
You can remove banks here too. The minus x will drop that lender.
Changing banks will not have an immediate effect on your entire inventory. It will take a little time for everything to recalculate with the new lender’s programs. However, individual vehicles can be updated by making any change to the pricing, zip code, or any other editable number that will impact the deal structure.
