Pinout Diagram Error.

[Squirrel]

The diagram and pin out list at this link:
http://pinouts.ru/data/pin_audiovox_8500.shtml
is incorrect with respect to the Audiovox CDM-8500VM (Virgin Mobile version)
By inspection of the supplied power supply, it can be seen that pin 5 is being used for (-) power supply connection.
The pinout I see is;
pin - function - Notes
1 - n.c. - Pin 1 is on the left with the keyboard facing up.
2 - (+)
3 - (+)
4 - n.c.
5 - (-)
6/22 - ???

Removing the cover from the phone confirms pins 2 and 3 are (+) and pins 5 and 6 are (-).

I felt bad for mouthing-off about the error in the diagram provided by our hosts here, so I researched the issue and can provide the following additional information.  

Pin Out Of "FutureDial" cable #47

This cable set uses the PL-2303 USB to Serial chip,
RS-232 signal designations collected from the following web link:

Pin One is on left, when looking into phone connector
with keypad facing "up" (away from the Earth - NASA).

the additional pin information...

A "universal" driver for this cable that supplies "basic"
support (using BITPIM) for the CDM-8500VM can be found at;

I used this cable to install an additional Ringtone following the information provided by this link;
