I have a 2009 Corolla LE (Canadian version) that has the satellite
antenna already on the car. I have a standard AM/FM/CD in the dash.

I was wondering if a Garmin 360 (using the external antenna plug in)
can be "tied into" the existing satellite antenna on the roof ?

If so, do I need any extra parts ? or a cable extension ? in order
to use it for my GPS?

Thanks

I am pretty sure that the short flexible antenna on the roof is a standard
AM/FM antenna and not a satellite antenna. If you are willing to
experiment, get an RCA jack splitter, unplug the antenna lead from the back
of the radio, install the splitter, and run the new lead to your GPS. You
will probably need some kind of adapter from coax to whatever the input for
the GPS is.

Different plug, Ray. I don't know about the Garmin, but the XM system uses
a different type of connection. If you have a wireless card for you
notebook (um, a bit archaic...) it's a similar mount.

If the car is equipped with XM from Toyota then the bottom of the antenna
is the satellite receiver antenna. It has a slighlty larger base than the
AM/FM antenna.

As far as receiving both signals at the same time, theoretically, I can't
see why it shouldn't. Signals are signals, and if the antennas are similar
then the reception is controlled by the receiver, not the antenna (we're
stepping into one of the few realms of 'gadget technology' I'm not all
*too* familiar with...).

If I were the OP I would contact Garmin and see if the XM antenna can be
adapted to the Garmin system. Either Garmin or XM should be able to
provide an answer.

The short answer is, yes, the satellite antenna (XM Radio, for example)
should work with your GPS. The antenna will not do both, but is should be
able to do one or the other.

I don't know if the connection is the same, but the antenna itself should
work okay.

You can mount your GPS antenna at the base of the windshield on the inside
of the car, and it will work fine. I know they say to put it on the outside,
but I sold GPS fleet tracking equipment for a year, and mounted a unit in my
car and had the antenna mounted to the 3rd Brake Light housing, and my GPS
worked fine. I had an XM Radio for a few years, and the antenna was super
glued to the dash board at the base of the windshield, and the XM worked
fine.

That will depend on the antenna installed. Some better ones are GPS/
Satellite radio combo. Maybe yours isn't.
