I have a 2002 Town & Country with a broken cassette belt. I replaced the original one with a thicker shorter one which broke after 6 months.

98% of my usage of the radio is to connect my iPhone and listen to podcasts and/or use as handsfree use of my phone.
What I would like to do is either/or replace the belt with the CORRECT one so I don't have to take everything apart again, but would like to NOT do that.
Does anyone know if it's possible to just run wired from a 3.5 connector (to plug the iPhone into) then to the input connector to the back of the radio for the in dash changer? Which is the small connector pins 1,2,6,& 7. Then I would just need to switch to the tape/cd player.
Is this possible?
Thanks
