One of those frustrating days. Was hoping to get all the components installed (bluetooth ULF, Sirius module, Alpine iPod adapter, HD radio module) and basically got nowhere because of missing some key parts. Ordered a bluetooth pairing button from some go to guy in Germany (none of the USA sites have this button and it does not show up on the OEM parts finder diagrams). Ordered 30 AWG Kynar wire from an Ebay seller so the Alpine iPod adapter never lets the iPod sleep and perpetually keeps it charging. This requires some careful drilling and soldering under a bench magnifying glass/light. See this link

Have any of my fellow ZHP owners done this wiring modification?
At any rate, looks like late this month to get all of the mods done.
