Does the iOS system have an amp? I have an AT4 non Bose iOS system and the dealership tells me that I can add the kicker sub and amp to it but not the 4 channel amp. Why is that?  Can I add an amp to the iOS stereo?

Sorry for the stupidity on this, but how do I find out what my truck has for IOS, IOR etc.?  Thanks for advise.  I have a 2021 GMC Sierra 2500HD SLT with outside trailer cameras.

2021 SLT will have IOS or IOT.

 

IOT is the one with Nav .

 

If you have the rpo code sticker in the glovebox it will be listed.

If you have the QR code on the door post it is likely included in the codes there (QR code list isn't as complete as the stickers were) 

 

2021 1500 sierra:

 

IOS    Audio system, Premium GMC Infotainment System with 8" diagonal color touch-screen, includes multi-touch display, AM/FM stereo, Bluetooth streaming audio for music and most phones; featuring wireless Android Auto and Apple CarPlay capability for compatible phones, advanced voice recognition, in-vehicle apps, personalized profiles for infotainment and vehicle settings.

EDIT:  I overlooked that you have a 2500 -- but the info is the same for 2500 and 1500
