You will still have at least two cables running from the GPS: one for
power and one for the antenna.

Garmin is claiming 5 to 10 hours battery life. Scratch one cable. (use
rechargeable NiMH, and most likely increase the run time)

Many have said their 295 gets great reception with no external antenna, when
mounted on the dash, or even the yoke. Scratch second power cable.

Looks like no cables to me, are possible.

I guess if you want to use the XM music output function, you will use one
cable, to go to the intercom, or earphones.
