Hello!

I drive a 2011 1 Series E88 and I have been trying to fit an aftermarket radio (Pioneer MVH-330DAB) but i'm running into issues getting it to power on.

I purchased a connects2 harness after finding out the one that came with it didn't work but I need a constant 12v source for it. I read that I can use a fuse-tap to power it on but I ordered 30a after reading these are usually constant but I think these are too much for a radio with a 10a fuse.

How can I get power to the new receiver? Don't really fancy connecting to the rear battery if I don't need to. I can order a 10amp fuse-tap but not sure which slots are suitable for constant 12v or if this will even work.

Thanks
