Thread: 00 GT-wanting to put touchscreen in

I'm new to the forum and need some help. I have a 2000 GT sedan and I'm wanting to put a touchscreen in it to replace the factory radio (not bose). My question is what is the largest "din" size that will fit if I cut out the cross beam between the stereo and the temp controls? I am prepared to do some light modifying but do not want it to look ghetto. Any help would be appreciated!

Double Din
