Thank you for gupdate.gcd.

I compare your gcd and gcd from Garmin server and this gcd is the same.
Maybe where2 have 2 nuvi 70 with different hwid.
I send again mail to Avis if he can provide gupdate.gcd from nuvi 780 with hwid 872, on first mail no response i dont know if he response on this mail.
