what would be the best solution for canadian tl if i want to get mp3, dvd player and ps2 with a switch?I have 04 tl with navigation

I know the PIE converter will not with our canadian tl, but what are the other options?

Do I need Blitzsafe V.2X and Soundgate AUX3 at same time or only one of them is needed?

I have Dom's dvd-navi conversion done with FM moduler now and I am not satisfied with the sound quality.

any help would be aprreciated

Thanks
