It's a china made 2Din DVD with Navi but no maps. I believe it's running on a Win Ce platform with 800x480 resolution and comport 2 and baud rate 9600.

1. Where can I download the maps and run in the SD card? (i prefer hong kong/china map)
2. How do I install it or run it in my system?

I prefer everything in english and don't want any chinese map.

Much appreciate any inputs and feedbacks.
