I bought a phone case from Ali***ress for my phone and only now realized that the rear insert is not actually magnetic. I already checked it with a multimeter set to resistance (ohms) and confirmed that the part is metallic. I'd like to remove this metal insert and replace it with a truly magnetic one. I already tried mechanical prying with a blade but only ended up damaging the surrounding plastic housing.
Which solvents or debonding agents could be used to detach this metal component from the plastic substrate? Unfortunately there're no identification marks on the plastic, so I cannot determine whether it is ABS, PC, TPU, or another thermoplastic.

So far I’ve been using an old 3.5 inch Garmin navigator in my small left-hand-drive 2001 MK4 Ford Fiesta, mounting it with its suction cup holder on the windshield just below the rearview mirror. Now I’d like to use my 6.5 inch smartphone as a navigation device, so I need to buy a car mount. The type of mount depends on where the phone is positioned. I’m not sure whether placing it below the mirror is still a good option, mainly because it’s wider than the Garmin though its height is the same, anyway I’m concerned it might obstruct too much of the road view.

I’ve attached photos of the small cabin with my current 3.5" navigator installed, along with a close-up of the instrument cluster showing my 6.5" phone resting in place.

What's the best mounting position for a 6.5 inch navigation device in a small car interior?
