Assalamualaikum, I am usually faced with a lot of waswaas, worry, overthinking and i think i may have OCD, i want to go into the business of selling car head units(display screens for car center consoles) that replace old stereos and they are usually used for navigation and making phone calls while driving(basically like a mobile phone in a car)and some people use it to listen to music(probably anyone who listens to music will) even though they can listen to the music with there old stereos,i keep on worrying that because some people will use it to listen to music, this makes this business haram for me to engage in. Please advise on this and also how to deal with the compulsive waswaas and overthinking. May Allah bless your efforts.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Since these screens are originally made for permissible purposes, then there is no harm on you for trading in them.
