installing oem navigation radio

I have an 04 trailblazer without the bose system and want to install the nav unit. Can the unit be installed if I get the bose amp and use the stock speakers

Just want to let you know people do see your question, but unfortunately most of us have no idea!! :)

bump as i need the same answer

I have an 02 tb ltz. I plan on putting one of these nav systems in soon as i can find a good cheap price on the head unit itself. Theoritcally it would bolt right in. Theoritcally
