F.O.Q. (Full of questions!!!)

First, is the Oncore UT+ the same unit as the M12+?
And if not, are there significant differences between
both units? Briefly, would you suggest me to spend
more on a M12+ than a UT+ ?? (or let me wait until
july for the allnew M12M...)

Also, Randy Warner suggests only versions 2.2 or 3.2.
What happened between versions 2.2 and 3.0 ? (it looks
like that there have been major hardware changes...)

And... Is it easy to reflash one of those units? (do
we need special hardware, and are reflashing software
/ firmware easily available on the Net?)

Finally....On R5122U1112 (version 2.2), how is the 100
PPS behavior? (if i refer to the PDF file uploaded by
Randy, a significant correction has been brought to
the 100 PPS only on the version 3.2 firmware...)

Thanks and 73 de Normand VE2UM.
P.S.: Are transactions accepted on this forum? (for
example, asking anyone if they have GPS boards for
