G3X Touch XM version

I MUST ASK---YOU NEVER KNOW ....

If anyone accidentally ordered the XM version and would rather have the NON-XM, I will trade and pay the difference.
I did not realize you could not upgrade the software, whole different unit I guess.

I'm not sure I'm following. You can just choose not to enable the XM subscription and then the unit is exactly the same as the non-XM.

The non XM version does not have the physical XM receiver built into it.

Yes, you can choose not to activate the XM if you have it but don't want to pay the fee.

My understanding is that the cost is in the hardware and the license to use it back to the XM gods.
