I put a Scion head unit in my 87. It works great, however there are a couple issues.
The Scion head unit is wider, so you will need to make the hole in your dash wider.
In my 87 I had to change the connector on my wire harness, but I think the one in your 97 will work(I can check this tonight on my 97)
I think there is a thread on this somewhere, but I can't remember if it is this forum or another
