Hi

New to here so I apologise if I've posted this wrong, or if something aimilar has been covered before. My phone wouldn't let me search.

Basically to sum up. I purchased and installed a new top dash aftermarket stereo in my 2007 3 series e90. Everything works with it as it should tbh. But a week ago last Friday my car electrics started to play up. Any time I turn the car off, the lights are flashing on the dash and old stereo. If my headlights are on they flash, heads lights constantly trying to adjust up and down like on start up. I worked out yesterday that is it is the new android tablet causing this. When I disconnect the main cables that come from the old wiring harness it stops.

I'm just wondering if anyone has any insight I to why it may be doing this. Can provide more info upon request. Wasn't sure what to actually get to attach, but I have a couple of vids and the some pics.

Cheers all!
