Hi all,

I recently changed my amplifier due to water damage because of heavy rain, the amp i got from scrap is for GS350/GS450h 2013-2015 (part #86280-30670-1) this what was available and requested one to match my part number an hopefully will get it soon.

Everything is working fine except for right rear speaker(not a concern easily replaceable) and the mic, connecting the phone through bluetooth playing music all good.

Only mic, when calling or receiving a call no one can hear me but i can hear them clearly.

I checked most forum posts and none have this issue in 3IS.

I tried disconnecting the battery overnight, went to hidden menu but mic test not showing any signs it's working.

Is it because the amp is not for my model? Is there a fuse i need to check? Or do i need to replace the mic? Which is insane!

I have Lexus IS 2015 fsport.

Appreciate your help in advance!

My amp was made in Thailand, part#86280-53190
The amp i got is made in China bruh
