H2 Xm Question

[IPStack]

Alright, I am going to go out on a limb and post a H2 related topic in here (j/k, here come the flames)

Put the GM factory XM kit in my 04 H2 with the Nav system. Everything works perfectly, but for some reason the sound (only on the XM) only comes out of the drivers side (front and rear) speakers only.

Per the directions that Klaus gave me and the ones supplied, everything seems fine....any gurus out there have any idea why this would be....
