Just finished up with the install. Easy to do. Only one additional step I would add, that's not mentioned in the instructions. Remove the passengers backrest and if it is OEM i have read you should NOT push in on the screws when reinstalling the backrest, because the nut plates may dislodge.

My question:

I have not activated the radio and am wondering.

Do the parentheses around (((XM))) change from 1, 2, or 3 of each on each side to denote signal strength?

If not, is their a signal strength indicator at all.

I ask because my Garmin 665's show signal strength.

Thanks
