With 0 checksum errors and sentences looking well formed (to me), what is wrong?!

Thank you in advance for help. I really need this to work.

(running the "test_with_gps_device" example results in all * * etc.

@fscii i had the same issue. The reason is because the GPS you are connecting is configured to receive GLONAS messages.

In TinyGPS.cpp change the define statements at the top to

define _GPRMC_TERM "GNRMC"

define _GPGGA_TERM "GNGGA"

@prlombaard Sorry I didn't see this for so long but thank you for the info. I just went back to revisit some GPS code and came across your answer before I got started. Thanks again!

PS: If author is looking I'd like to suggest moving these defines into the users code so library source doesn't need to be touched.
