i have found this radio http://www.kijiji.ca/v-view-image.html?adId=1015599029&image=1&enableSearchNav igationFlag=true`

anyone know if this part can fit ont my Aztek ?

That'* a double DIN radio. It will probably fit, but it won't work unless you take it to a dealer and pay them to reprogram your VIN into it. Otherwise, it won't work.

once you add dealer programing in your normally better off buying a aftermarket unit from crutchfield or sonic electronics, they give you the adapters and they have a ton more features and sound better than any gm radio.

^He'* correct. Your better off with an aftermarket unit that works/sounds better then OEM.

okay... bit the price for a GPS / Radio / Bluetooth / mp3 system is verry high... i need one but with a cheap price lol

you arent getting a oem unit cheap with gps either. its better to have a separate gps, you can get a decent HU, i got a sony HD,aux, usb, thats designed to sound decent with stock speakers for 120-130 off sonic electronics and i have a 5in sony gps i got from the factory outlet for like 70. both have been flawless but if either go im not stuck replacing everything.
