Help on Chinese HU install

I got one of those cheap Chinese HUs and having issues on install. I already sent the seller an email with these problems. I also re-disconnected the battery to reset but no help. The problems:

1. Two of the connectors from the radio aren't compatible with the car's connectors. Any idea on a way to fix this. I'm hoping it's only for the steering wheel control buttons. Maybe it's the cause for all of my problems?

2. GPS doesn't work at all. Maps come up but no indication my location exists.

3. AM radio tuner goes from 702 to 711, etc. skips all the in-between numbers.

4. No idea what the password is. Tried 0000 and 1111, etc.

5. Bluetooth works, which is a real good thing.

6. FM works.

7. The DVD disk doesn't go all the way into the unit. Goes in about 95% of the way.

Any help is appreciated.

FYI, the seller sent me an email for more details. He's also supposed to send me a better set of instructions. We'll see what happens.
