touch screen sync signal

I ordered a Pyle universal gps touchscreen compatible ( model plnvb26). It has two video outputs, RGB & composite. The RGB has a sync signal, is this signal for video display or is it for the touch screen? My Pyle dvd display (plts79bt) is a touchscreen and has a composite video rear input with matching audio in, but no RGB input. I would like to know if it is possible to mate the two with touch screen? The dvd main menu does have a gps icon(owners manual says optional).Working with Electronics since 1980.

I'm not familiar with either of those products, but typically the RGB signal has a sync signal with it. This is commonly referred to as RGBS. More then likely the two video outputs are video only, no touch screen capability. The two different touch screens will not interact with each other.Kevin Pierson

Thanks for the reply. The DVD is the only one with a screen. The gps is a universal system that is listed touchscreen compatible, but I am unfamiliar with that technology. The manual says to make a selection, tap the screen or use the remote. My guess would be if the head unit has a touch screen and the gps is also, then the A/V channel is bi-directional. Can anyone confirm this?Working with Electronics since 1980.

I found out the Pyle GPS only works touchscreen with the older Pyle DVD units as the it must be able to accept the 20 pin connector that carries all signals. It is most likely a RS-232 serial port connection (or USB). I will look into identifying the pins and work on an interface to the head unit.Working with Electronics since 1980.

Maybe try mp3car.com. It's right up their alley.

Thanks i will.Working with Electronics since 1980.
