Just bought a after market stereo

how to remove the original stereo. Ive got a fiat bravo 1997

Can you get a picture? My guess is, there are some holes in the front of original unit. If so, you'll need to poke something in there - strong wire, like from a coat hangar - to release the lock, and pull the headunit out whilst pushing the wire in firmly.

Welcome to the forum

thanks for the help. And yeah another question which one is the tach terminal. I found a black box under the driving wheel but im not sure if its the right one im trying to install a rpm shift light.

Might be better to post that question as a separate thread here - https://www.fiatforum.com/bravo-brava/
