I have a 2003 Tahoe, and I am trying to find a good place to put the antenna. I would prefer to keep it somewhere inside the vehicle if possible. Any ideas?

In the center or corners of the dash on the metal pad that it comes with

or under the dash itself

Can I tuck it away behind the unit beneath the dash?

Plenty of people on here have gotten crappy reception under the dash. Some cars it works fine, others it won't

I have mine under the dash, and its been fine. Make sure you either mount it on a metal surface, or use the provided metalic sheet and try finding a spot as high as possible and with as little obstruction above it as possible.

Up to you tho. I figured it'd be a pain to run the wire up through the dash so i chose not to go that route.

velcro it on the top in middle of the dash.

i have a 2004 yukon and its pretty much the same thing as the tohoe,

i have mines under the dash on top of a peice of metal and it gets 8 sats most of the time and i have no problem, but i did have to take my dash apart, but it was not to bad to do.

What does the metal plate do? I didn't use mine and I still get 6-7 sats most of the time.
