Radio is a double din or single din?

I think is double din.

It comes from the factory equipped with a din and a half radio.

These features contributed to a good 2 din stereo: 1. Wider touch screen for your easy access to touch and watch. 2. Bluetooth function enable communicating with your mobile phone conveniently. 3....

To answer your question, Yes. I wondered the same thing, I went to BestBuy and I went to the automotive section, got on the Car Finder computer they have back there and it says the Oldsmobile Alero...

The difference is that the oversized single din is just that - OVERSIZED.
