Scott - I have a T2-301 connected to your T2-301 Serial & Power
cable with your serial splitter cable connected to it. I have a Nuvi
350 connected to port A (red) and a non-display GPS receiver
connected on port B (blue). All appears to be working OK, but 
the T2-301 is warm to touch. The T2-301 was transmitting
every 60 seconds while testing, but should be transmitting every
10 minutes now. I just popped the lid and felt all of the major
components. The back of the T2  board and the large shielded
enclosures were all mildly warm. None were hot. The ambient
temperature was about 22C. I just measured the current with a
GPS receiver connected. It was about 100 mA, but briefly
pulsed to about 12A while it was transmitting. The GPS alone
is probably drawing close to 100 mA, so I don't understand
why the case feels warm to touch. I would expect the T2-301
to be not much more than ambient temperature. Do you think
there is anything unusual going on?

I'm probably worried about nothing. The radio was powered
by a 13.8 source while I was testing. It was easier for me to
measure the current by changing over to a battery. The voltage
was about 12.9V and the T2-301 was noticeably cooler to
touch. Still, any comments?
