I bought TEDELEX from OO.com.au, which is a very good unit for a good price, it has the following features for navigation.

- SD Card slot / USB port
- GPS Navigation Ready (i have to buy a GPS Unit and connect the cable to detect the GPS)
- Built in TV/AM/FM Tuner

Car DVD system Model Details

If i want to use this for general navigation then
1. Which software should i use?
2. How to install ( In SD card)?
3. How to activate (fast activate)?

or let me re-phrase, if i want to make use of this in CAR DVD system as a navigator by installing software ? what should i do?

Thanks in advance and look forward to your responses...
