Q: How is a completely stripped Yaris LB wired for sound?

[xed]

Hi all,

I am considering one of two options. A LB with the convenience package and one without. Here's my question.

If I go with no options at all (i.e. not even the convenience package) then what does Toyota still provide as far as the audio system goes? Does the car still have speakers and everything is wired up and ready to go but it just doesn't have a head unit?

The Toyota documentation states that it has an "prep" package if it's stripped but I didn't see any other info.

My thinking is that if I plan on putting in a new head unit then the convenience package only get's me 15" steelies instead of 14" steelies so there isn't much point in bothering. That being said, I don't want to buy a no option LB only to find out that when I get it there are no speakers in it or (even worse) there is no wiring already run.

My hope is that if I buy a no option LB that when I get it I'll look where the head unit goes and see the normal wiring harness sitting there.

Can someone who bought a no option LB tell me what the deal is? My guess is that all the speakers are installed and everything is wired ready to go; just no head unit.

Thank you in advance.
