Pls. help. I like to exchange original Ucrap 3.0 for nicer unit

[RidgefieldRam]

I got nice d-din head unit with NAV, BT and is SXM ready. I already purchase the replacement bezel, antenna adapter and wiring interface but do I lose my SXM radio with the old unit and have to purchase new SXM tuner or the old tuner can be disconnected from old 3.0 Ucrap unit and used with new one?

Thanks for any help.

Martin

ps. I know, I know speakers are next !
