[Q] qtek 2020i usb connection pins plan

---

Hi you all. as Y may know a Qtek 2020i has 30 or More connections pins and at least too usb connections, one for host and one for PC sync. I have 2 cables for host (used for GPS car kit), but no sync cable.To save time, money & for curiosity reason, I would love to find out what all connections pins are there for. so if somebody knows, or where I can find it on the net......I have looked for many hours, but no result
GGGGGGraet web site.thanks guys beforehand
bay the way i have a small problem my Qtek: when changing Sim or battery, I lose all data, like H.reset. cold it be the inside battery, (shows always 100%) if so is it possible to find it somewhere. its a 3v recharge.
I saw some clips on you tub whit people using win m 6.5 on a Q 2020i. Is it possible ?
