Need help sending Coordinates to app using Neo-6m and HC-06

Hello, I'm trying to send some NEO-6M coordinates to a label box using the HC-06 Module, but it seems it's not working. Can anyone help me out? I'm also using the Arduino Mega
In this case, I'm using the NEO 6M as Serial2 and HC-06 as Serial3 by the way
