I have a DEH_P77DH. Great HU BTW, tons of features. Anyway, it has the pioneer DFS alarm built into it. I'd like to use it. It wires into door pins and has output to relays for horn and starter lockout if the unit isn't disarmed . Anyhow, does anybody have any familarity with the DFS system, because after the manual tells you how to install the starter lockout relay, the next page says: "Avoiding trouble. You may not be able to start the engine even if you operate the unit correctly" and continues to recommend a starter lockout switch/relay bypass.Which, pardon my words, seems really stupid. Anybody have a clue why they would recommend that? Is there a problem with the DFS, or are they just trying to catch people who may not have wired it properly, or they just want to avoid a raging phone call from some guy on the side of the road who can't start his car?
