Update - I've lowered my price to sell: $300 plus shipping and added pictures below.
IO6 Radio and HMI 2.0 Modules were removed from my 2015 Sierra SLT - Factory Navigation, XM Satellite Radio, Weather & Traffic subscriptions available through SiriusXM. Includes USB Module/SD Card Reader that resides in the center console.
May be a plug-n-play upgrade from IO5 trucks. Harnesses not included.
Removed from 2015 GMC Sierra SLT - Excellent Condition
