Car toy(s) for 15 month old?

[crl]

We are going on vacation soon and will be doing a 5 hour drive each way with our 15 month old. I am sure she will sleep some of it, but not all.

Suggestions for a toy or two that we could use to entertain her. Electronic beeping, etc is okay as long as it isn't too obnoxious.

Thanks!

The best toys for my almost 1YLO are his brother and sister! Seriously they entertain him the whole drive! Can you take your DS toy shopping with you and ask him to pick out some toys that he would like to use to help entertain his sister? Otherwise I bring soft books and his Baby Einstein take along tunes and then let my 8y0 DD put together a bag of stuff for him.
