There are some people working on aps that will grab the

I want to hear more about this and particularly how we can crosslink the
MotoTurbo texting with APRS texting!

MotoTRBO is just a catchy trade name for the open-standards DMR
(Digital Mobile Radio) originally defined and documented by ETSI
(European Telecommunications Standards Institute). The DMR standard
provides for the transport of a 4800 bits/sec data stream, mostly
used for digital voice, but often also used for data as well. The
name MotoTRBO was invented by Moto marketeers to create the
impression that this protocol is somehow unique to Motorola. <br>
<br>
On the other hand, Moto's text messaging and GPS posits ARE
proprietary applications layered on top of the generic DMR 4800
bits-per-second data stream. There may be serious
licensing/intellectual property issues surrounding these formats if
you reverse-engineer the data formats involved and create non-Moto
third party apps to decode this stuff. [Thank the vile Digital
Millennium Copyright Act (DCMA) for this situation that
criminalizes reverse-engineering software functionality, even if you
then write completely original "clean" code to achieve the same
ends.] <br>
<br>
However, I don't know the legalities of taking the data spewed out
of a licensed Moto decode routine (figure on major bucks per radio
for the privilege) and then re-encoding it in an unrelated format
such as APRS. <br>
