Looking for cyclometer/gps with specific features
 

Here is what I need:
ANT+ (power, cadence, etc.)
GPS - need not have full mapping, but at least able to take a tcx file/route
Ability to disable auto pause - i.e. I want to unit (clock) to continue until I manually stop/save
USB chargeable
Ride start with user prompt, not automatically based on movement
File uploadable to popular online analysis tools (Garmin Connect. Poweragent, Cheetah, etc.)

I have an 810 - way too quirky, won't use
Joule GPS - can't do continuous time

The Garmin 500 may fit the bill but can't quite discern from the online manual if it does continuous elapsed time.

Might there be another out there?

Thanks -

You can turn off autopause on the G 500. Great deals out there on refurbished units.

The 500 does all you want. Turn off Auto-pause and it's entirely manual.

Thanks - went on my first ride today with my refurbished unit.
BUT - I never imagined the G500 can't record and be charging from my hub gen!!! Why oh why would G do this?? (My Joule GPS & G810 both have this dual cpacity.)
There are post out there talking about pin 4 & 5 and GND. I am not an elec eng.
Can someone simply give me the Amazon links for the cable and the adapater(?), or the Gomadic part number(s).
Charging while recording is critical for long brevets, and frequently there is not time or the facilities to recharge off the bike.
Many thanks -
