I want to cancel the function on the base radio that lowers and increases the volume with your vehicle's speed. I did not get a manual when they installed it and I can not stand that feature. Any help would be greatly appreciated...

It's the Audio Cont button. The button is on the left hand side. Just keep pressing the button until you see the option. Then, just turn it off. I believe default is set to low. This is for the base unit...

Thanks for the info!!

^^ and i believe it's the "ASL" option

^^ ASL... yup.

(Automatic Sound Leveling)

yep, that's it!

Can this be done on the premium sound system?

Yes. It is the same ASL feature and is variable from the stock HU's main menu. If you thumb through the main menu, you will notice a tab for ASL. In this screen, you can adjust the sensitivity of ASL. Set the sensitivity to "Off" and you're in business. 8)
