Radio/gps dead on my 2016 IS200t

[jakesigue]

Hi guys, new here....I have a 2016 is200t. I accidentally jump started my battery with wrong polarities. Did few cranks b4 I caught it. it was night time, cold and in rush. Was able to start the car after I corrected the negative and positive side. But now my radio/GPS doesn't power on. Checked the fuse for the radio under the steering, its not busted at all, what else to check and to do??

ty in advance for the help

Did you do a resistance check of the fuse with a multimeter? Did you check other fuses?
