Answer 1

I think that Sirf receiver is by default in binary mode, and that you have to put it in NMEA mode explicitly.

Answer 2

I don't see you are checking port settings.

Default settings for NMEA over serial port is speed:4800stopbit:1 parity:none.

Check it on the device.

Answer 3

Try using the NSData's ability to print itself as bytes via the description method.

[outputTextView insertText:[data description]];
