Hi<br>Prior to removing the HU, all the threads I've read indicate I need to have the gear shift level (automatic) in Drive in order to have enough room to remove the HU. The engine has to be on or if the eengine is off, the key must be in the accessory to move the shift lever. My old 98 V70 (RIP) had a shiftlock defeat button that I do not see on my XC70.<p>When removing the negative cable from the battery cable from the battery the key needs to be in "O". With the key in "O" the shiftlock function will not allow me to move the shifter from Park to D.<p>Since I can move the shifter with the key in the accessory positon, engine off, can I safely remove the cable from the negative terminal?<p>Seems like a Catch 22. What did I miss in all the threads that have addressed removing the head unit? <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> <p>Sorry to ramble on...TIA<br>Ozzie

Re: Removing Head Unit (Ozzie)

I don't recall having to move the shift lever out of park when I removed my HU. I may have forgotten since I did it a year ago, but I don't think it is necessary. But I also didn't remove the battery connection. As long as you dont discontect the ECM you don't have to worry about this. I reccomend reading a couple more threads on this.<p><br>-Luke

Re: Removing Head Unit (luke8302)

It looks like I forgot. You do need to move the gear selector to the rearmost position. If you plan on removing the battery, I would do this beforehand. You need to put the key in accesory mode to move the gear selector. This has some posts about this issue. <p><A HREF="http://forums.swedespeed.com/zerosearch" TARGET="_blank">http://forums.swedespeed.com/zerosearch</A><p><br>...Sorry for the wrong answer initially<p>-Luke

Re: Removing Head Unit (luke8302)

Yep, luke8302 is right - move the shift first. I, of course, disconnected the battery first on my initial attempt to remove the HU in my V70 and quickly learned a lesson... I remembered when I did the job on my S60 but then it was a blistering hot day and I couldn't lower the windows... Then I found I needed a different connector to splice a couple of wires and had to go to the hardware store and couldn't set the alarm... The moral of the story is - preparation!

Re: Removing Head Unit (thevicar)

When I did the install, I discovered that I could move the shift lever on the automatic out of park into drive or manual mode with the battery disconnected as long as the ignition key was turned to the "II" position.<p>Prior to removing the battery, I turned the ignition key to the "O" positon and let it sit for 10 minutes.<p>Ozzie (an old PK)<p>"God bless the Anglican Vicars for sheparding their kirks (and the government for their stipend)!"

Was leary to disconnect the battery- had heard possible reprogramming of radio, etc. On our V70 '04 I put the key to position I until I got the lever moved, then turned the key off while working on the car.

Re: (phuz)

I know this is old news, but, Volvo states that you should disconnect the battery when working on the electrical system. <p>How to Disconnect<br>Step 1: Turn the key to position "O"<br>Step 2: Disconnect the battery negative lead.<br>Step 3: Wait 5 to 10 mminutes before disassembling connectors or other <br> electrical equipment.<p>For automatics, the key can remain in the ignition switch and the gear shift lever can still be moved after the battery negative lead has been disconnected. <p>To reconnect the battery negative lead<br>Step 1: Turn the ignition key to position "II".<br>Step 2: Connect the battery negative lead.<p>The only thing that needs to be reset is the clock.<p>Check <A HREF="http://www.vovlocars.com/accessories/ii" TARGET="_blank">http://www.vovlocars.com/accessories/ii</A> for an ever increasing list of volvo accessory installation instructions. <p>For the true Volvo purist, you can even get the instructions in Swedish!<br>Ozzie (.25 Swede, .51 Ford, .24 Hot Air) <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: Removing Head Unit (Ozzie)

As many Volvo engineering details - simple, once you know the trick. First, pull the pencil holder straight out. This can be done by inserting 2 flat screwdrivers between the ends and the console and pulling the piece forward. The plastic ring around the gear shifter is actually 2 pieces. The outer is held in place with tabs at the four corners. You can raise the two assembled pieces far enough to see the tabs on the bottom. The inner piece - with the wires attached - stays. Remove the outer piece, and you will have room to work. I just turn the key on "accessory" with the motor off. Hand brake applied, and put it in drive. That will give you plenty of room to pull the climate module out of the way (it does NOT need to be disconnected) and then pull the radio.

Re: Removing Head Unit (hjpress)

Couldn't have put it better myself. Just one thing to add: get those fingers good and strong because getting the HU out after removing the CC unit can be a test of strength. On my recent Bluetooth fit I needed to remove it (for the second time - iPod connector a month ago) and I very nearly dislocated a couple of fingers. There are two nasty little clips holding the CC unit snug to the HU which are fairly tight, but then the top of the HU pushes up and under a lip and boy, can it go in tight! My first job after removing the two is always to switch on the ignition to see that it all still works!<br>This from Steve, Isle of Wight, UK. hjpress can vouch for me...;-)

Re: Removing Head Unit (hjpress)

I believe the HU/CCM's, with the plastic "wood" surround, comes out as one unit. <p>That is the way it is with the 05 XC70. <p>Ozzie <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/redface.gif" BORDER="0">
