It's easier, but the aprs spec would let you hand -decode this, but it 
"looks" like a mic-e packet to me. That's why Mic-e is useful compared 
to sending raw NMEA strings out on the air - very comressed.

I run a pic E ... if you findu my -9 the look at raw data you can see 
what mine looks like.

This is a typical one, with me in Corpus Christi, TX:

Raw packet: WA2MCT-9>RW4Q8T-5,KD5UJY*,KD5UJY-11*,WIDE2,qAo,K5COD:`}2Vl#Hk/

The k/ indicates my icon is a red truck.
