I am using an MC55A0 withe SR Blockbuster engine to scan Vin #'s off of car's through the windshield. It usually isn't an issue until the sun comes out. It is then hard to see the aiming pattern and to get a good scan. Are there any parameters that I can modify to help with this (In DataWedge)?  I know there is no longer an option for an Aiming dot, but am looking for anything that can help out. Thanks.
