Hey guys! I'm looking for some info about the BeSpoke upgrade for the Pioneer HU. I have a 10 series tC w/ Map as a button option; which always says when pushed "BeSpoke Premium Audio is not installed Please contact a Scion dealer for upgrade details." Now I've been trying to research this, and I just wanna know if I need the ENTIRE Nav add-on [https://www.ebay.com/itm/...T-PLUG-PLAY/274322020313] or if I just need a simple Nav antenna similar to this [shorturl.at/HLV08] Any insight? Thanks.
