I have an 04 Tacoma and I am interested in installing xm, and I am looking for some input on the best syestem to buy and where is should mount it.
Here is my only stipulation, I want to keep the stock headunit for so don't tell me to buy an xm ready headunit.

 

Check out this website for all the information you need. Look into a unit with a built in fm modulator that will allow you to tie into your headunit with no large modifications. There are honest reviews of the units for you to read.

 

Check out this vid from crutchfield. They install the satellite antenna on a tacoma. It should give you some idea of what to expect.
