Question Is there any way for me to replace this Bluetooth interface?

[Jarvice]

On this head unit this interface pops up whenever I do something over Bluetooth with my phone. As you can see in the tabs underneath, this app is responsible for handling calls and music over Bluetooth but it's so unbearably ugly that I'm looking for a way to change this interface. I'm hoping I can either switch this app altogether and set a new app with the same functionalities as my Bluetooth default, or change the background and color to something else. Though I couldn't find any settings to change this background so maybe I'll have to dig deeper to replace that background image and color somehow. At any rate, please help me get rid of this!

It's completely dependent on the type of head unit you're using, but unless it's a customizable UI or Android base that can be modified at the OS level, I'm afraid there's not much you can do if the stock options don't offer that.
