I have an 06 g35 and doing a xm tuner install tomorrow from pioneer. My question is will the antenna work under the dash or on the rear deck instead of being outside my car?

 

has to be outside.. i tried and got horrible signal

 

If your car has factory XM you might be able to reuse the external antenna. It'll be wired into the trunk and bolted to the bose amp under the trunk mat/plastic pieces around the tire.

I don't know if the satellite audio is that different, but for reference a GPS antenna (for nav) will work inside as long as it's on something metal and not too obstructed. A popular place for that is under the panel in front of the clock. Not sure if that's where OMGHI2U tried to mount it, but it's easy to try and test signal strength real quick before you decide.

If all else fails, take a look in your trunk, might get lucky and have it plug up easy, haven't tried but I know the tuner is back there if you were wired for it and the connection looks similar.

 

XM/Siruis antennas are pretty sensitive (atleast the ones ive worked with)

almost everytime the antenna had to be mounted outside the car

GPS works inside with minimal problems

 

There's got to be a way to mount them that doesn't ugly-up the car.

 

Mounted it on top of dash by the clock so far so good just sitting there on the vinyl drove all through town not one cut out yet

 

Was just a guess, but I was forgetting that it was a more constant data stream. Sounds like he got lucky though, so far atleast.
