i found a buy for a 2002 pontiac grand am gt Monsoon CD/Tape/FM/AM head unit. will this hook up and fit into my 97 Monsoon system? Like will this fit into the dash slot? Please answer ASAP not sure how much longer will be available

I think they are both 2 din units... I don't see a reason why they wouldn't work, unless the connectors are different.

the grand am gt unit is 2 din and the formulas is a din and a half. It would fit if you were willing to modify your dash trim around the radio.

oh yes. The bird is 1.5 din... my mistake
