Where to tape for Switched Accessory Power

Installing the "portable GPS Pro" mount to use a standard modern Garmin GPS and I need to tap into Switched power and ground.

Ground is easy, brown wires everywhere, But I cant for the life of me find where a good switched power connection is. What color wire am I looking for and is there one going to the radio?

thanks!

Edit: I just confirmed that #4 is indeed the spot that's switched. It's also unused. I used a fuse tap which provides a clean, safe, connection.

Violet with a stripe is usually switched power. Best to get it from behind the radio.

Violet with a white stripe on the radio plug is the right answer. Perfect spot to tap in to get switched power for the BMW GPS kit. Wished there was a cleaner spot for the ground wire, but I connected at the radio enclosure using a screw. Funny how BMW supplied and expected me to use a wire splice crimp instead of a proper connector. MAke me think their GPS kit was an afterthought.

Thank you everyone for your help.
