Calling tech gurus out there!!

I recently got a Philips PET1030 portable dvd player. I was going to install it in my car so to entertain my kid especially with the crazy traffic, nowadays. Since I got it from the US, it's configured for Region 1. My Region 1 and pirated stuff works fine. But I can't play my Region 3 dvds. Would anyone know how to configure this particular model to multi regions.

Thanks in advance.
