The 6FL is the MULF-High. You do not need a TCU if you just want the 6FL and Bluetooth. If the TCU is installed with the MULF High then the Bluetooth function is taken over by the TCU.
The GSM TCU is required if you want access to the Assist Online services ($200 a year Convenience Plan). I have not been able to receive Google Maps messages with my CIC and GSM TCU, but I do receive the Online services.
