2001 BMW 740I Sport - Tuning the stock navigation sound quality?

Hey, I have an '01 740i sport and I was wondering if anyone can give me advise on tuning/ adjusting the stock equilizer on the Navigation unit.

If anyone could share their setups as well that would be excellent. I just want to increase the Bass and have a setup for Rock, one for Hip Hop, and one for Trance music. Since there are 3 custom slots after the 3 pre-made setups.

Any insight or advice would be well apreciated. Thank you.
