Audiocontrol HPX vs. magnets

Considering using small magnets to secure a cubby door to the front of an Audiocontrol HPX in-dash 1/2 din processor (the cubby door is hinged to move up/down - this will secure it in the down position).  The idea of magnets vs. electronics kind of freaks me out tho.  Does anyone know if this is definitely a good or bad idea?  I know in theory it's not a great plan, looking for some actual specifics.

magnets are 1/2" cubes, neodynum, 2 of them, one at each corner of the cubby door that would contact the front corners of the HPX face.

Oh, whoops, meant to say 1/8 inch square. I don't think I could open it if they were 1/2"!

Using the Neo magnets b/c they're very small & strong, plus I had a bunch on the fridge.  They'll hold the door in the up position, it doesn't look like I'll need them for down, so nothing on the HPX faceplate. 

Just for the record tho, I finally talked to Audiocontrol this afternoon, their engineer said no problem with magnets on the unit.
