adding xm to Stock NAV unit

[dave4242]

Has anyone added XM radio to the stock NAV unit on an04 4Runner?
I have the Delphi Skyfi, but the FM modulator that comes in the car kit fits into the tape player. However, the sot for the tape deckmis behind the NAV screen, so it would not allow you to use the NAV screen (It would have to stay in the open position).
Are there inputs in the Head Unit for a CD changer? If so, there are a couple manufactureres that will allow the XM signal to be input there.
If there are aux/changer inputs, how difficult would it be to get behind the head unit to hook it up?

I have the same 04 Limited with a Nav. I am adding a Sirius JVC unit (Sirius so I can get the NFL games). From what I understand, with an FM modulator on the unit I am getting, you do not need to use the tape slot. The FM modulator is part of the cradle and sends an FM signal to an unused frequency on the factory radio. You tune to that frequency and receive the satellite signal on your factory radio. You only use the tape adaptor if you do not have the modulator. I am not sure about the Delphi XM unit.

The down side to this is the signal quality is "FM" in nature rather than digital that the satellite radio can produce. To get the best quality signal, you need to do as you suggested, plug the XM or Sirius unit directly into the aux input on the back of the radio. I also am interested to determine where that input is exactly and what type of plug does it take. (RCA or DIN). If I am forced to use the FM modulator type of installation, at least the factory 10 speaker system is quite nice and will give decent results.
