i2c access for the GPS was only considered when connecting the BerryGPS-IMU via QWIIC cable. However, we have had a number of users still want to use the BerryGPS-IMU while sitting on top of the Raspberry Pi.
Right now, you have two options;
1. connect via QWIIC cable and not have the BerryGPS-IMU sitting on the Raspberry Pi.
2. Remove the two inductors circled below.
If you want serial connection back, you can place a solder blob where the inductors where to close the connection. The GPS will still work perfectly fine without them.
BTW: in the next version of BerryGPS-IMU, we will include jumpers on the back so it will be easier to break and restore the tx/rx connections
