Question for those that have installed GROM
Is the behind the radio or in the trunk the preferred method of installation. I have an 2006 Z4. It's has the business CD head unit but it is prewired for cd changer in trunk so I think the wiring is their for BT3 but I'm wondering if a behind the radio install is easier or performs better? Thanks
