UTStarCom XV6700 and garmin etrex cable

Hi all...
I have had a Dell Axim for a few years. I had Pocket Streets installed
on it. I would take it on trips and had a cable that I could hook my
plain-jane yellow garmin etrex to it and it would act as a nice NAV
system in my car's cupholder.


Now, I have a xv6700 phone with verizon which runs PocketPC... I have
installed Pocket streets on it, but have searched the devil out of the
internet trying to find a cable that will connect my phone with my
garmin with no luck.

Any suggestions?
thanks in advance!
