Pioneer AVIC-F700BT Problem - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The ISO connector did have two connectors. One that plugs into the amplifier (blue\green\yellow block - only the amp wiring is used however) and one which attaches to the speakers (both blocks)

I Have spoken to him about the problem but he's stumped.

I pm'd trieullionaire and I have his connector and instructions already (I bought his kit from ebay) but the F700BT has 1 pre-out which is for a subwoofer only - so I cannot use that harness.

Could I gorund the amplifier by just holding some wire on the chassis of the amp to a ground point somewhere in the car to see if resolves the problem? Do do I have to cut the brown wire to the amp?

Thanks for responding.

I'm hoping that an electronics expert will also chime in on this thread...

I would try what you're suggesting if there is a way to push in a wire into the fat connector or the amp pin that connects to the ground. another way you can try this is to use one of those jumper clamps that allow you to connect a new wire to an existing wire. It's a plastic clamp that wraps around the main wire that allows you to conncet a new wire. Make sense? Connecting to the physical amp housing would not do it, I think.

The last set of details makes a lot of sense - I'm hoping True has the answer for you...

I know what you mean re: the plastic clamp. I have one spare as it happens so I could try that. Effectively the brown wire is still connected to the amp as normal but it'll be a Y shape with another earth lead coming out of it running somewhere to ground.

Will try this as soon as I get home tonight! It's 10 past 1 here and I'm still at work fretting about my head unit lol.

You can also try this - install a ground loop eliminator on the Sub Pre Amp outs from the head unit. You can pick one up at Radio Shack - not sure if they are in the UK.

Even if they are not being used? Which they are not.

I can get one however.

Hmmm I didn't know that so if the sub RCA connectors aren't being used it may not make a difference with the ground loop eliminator.

Steve - thank you for trying to assist.

I still haven't had any joy and on top of that the iPod connector doesn't appear to work (I bought the interface cable for it too) either.

I'm close to just taking it out, getting a new housing (do you know anywhere I can get one? I have the black leather option in the car) and going back to stock.

I plugged the Becker back in and it was fine - no whine. It's kinda doing my head in and the guys over here who sold me the lead are about as useful as a chocolate fireguard.
