  1. If you look under Input Signals for the alarm control unit, you should be able to see the state of the door/compartments/radio contacts, etc. Aftermarket radio perhaps? People often connect the alarm wire to the cage, thinking it is a ground connection, when in fact it needs isolating.
  2. If I remember correctly, fitting a 981 wheel & airbag on a 987.1 causes a problem with the horn. The 981 uses a hall-effect switch for the horn contact, and it operaties in the opposite sense to the 987.1. (Normally closed instead of normally open, or vice-versa). To make it work, I think you have to remove the airbag casing and turn the magnet over, making it work in the same sense as the 987.1. I think you can also get round this by fitting a 987.2 steering column control unit, but it is a more expensive solution. Fitting a 981 wheel to a 987.2 isn't a problem, which is what I did on mine. As for the cruise stalk, the 981 stalk is completely different, and won't fit a 987. Unfortunately, UK dismantlers know what Porsche charge for the stalk, and charge a lot for them. You are best trawling the US eBay site, as cruise was fitted as standard to US cars, hence dismantlers don't generally charge a premium.
  3. If you haven't got navigation, tI can't see any reason why you couldn't update the firmware yourself, with the using update DVDs. (If you had navigation, the old maps wouldn't work after the update). What I can't work out is what you mean by Version V. If you press INFO and SOURCE at the same time, it should show a numeric version number. Something like 2.20.
  4. I have only used PIWIS2 for coding 9x7s for cruise. I suspect that your indy may have been using a PIWIS1, which might not be up to date enough for a 2010 997.2.
  5. You shouldn't make any changes to the Gateway. Only the DME, Instrument Cluster, and Steering Electronics. Your profile says you have a 2003 996. In that case, look into the DME Vehicle Data, and check that the Order Code is entered correctly. For a RHD C4 Cabriolet, it should be 996611. Then do a FULL Control Module search, and code the instrument cluster and DME for "with cruise control".
  6. I'll take a look when I get to my PC in the morning. I might have some info. Failing that, it might be worth taking a punt on something like this: 05-08 Porsche Boxster S Cayman 911 997 987 #1085 Navigation DVD GPS Drive Unit WWW.EBAY.CO.UK Donor Vehicle: 2005 Porsche Boxster S. Vin# WP0CB29815U732083. Interior Color: Black. Exterior Color: Black. I can't really see why it wouldn't work, but even if not you could strip it and swap the DVD mechanism.
  7. I don't know the loader type offhand, but if you want it replaced try Maple Audio in Bath, or Cartronics in Surrey.
  8. Bear in mind the 2004 (MY2005?) will have a different starting point for the updates. MY2006 will almost certainly be Level B, or possibly Level C, and yours is Level A. Also, not wishing to be pedantic, @angusc you might want to delete the attachment from your post. @Loren is understandably concerned about Porsche copyright material being posted on the forum.
  9. I don't think reverse camera was ever an option on the 997 PCM3.0. On the Cayenne with PCM3.0 the camera outputs were connected to the TV tuner, and the TV tuner to the PCM. My guess is that you would have to code the PCM to add the TV tuner feature. Trouble is that this requires an Activation Code, which needs entering with a PIWIS tester. Not only that, but you would have to work out how to tell the PCM to switch to the TV input when the camera is required. There is a connection shown on the wiring diagram for the PCM labelled 'Back Cam' (with nothing connected to it), so that could be it. However, I suspect it is much more complicated than that.
  10. The option 580 2002 Bose amp is an oddity. It amplifies the speaker outputs from the head unit. The 490 option Harman (Haes) amp uses the line outputs from the head unit. Drop me a PM with your email address if you would like the wiring diagrams.
  11. Are you sure you have an amp? Option code 490. The reason I ask is that you have speaker wires - the brown plug. The black plug has the power connections. The blue-green-yellow plugs go into the orange Metra socket, but only if you have the 490 amp. It looks to me like the wires to the green plug might be for a CD Changer.
  12. The menus are different, and you won't get some features of the dot matrix cluster shown in your 2003 owners manual. You will get: Range on remaining fuel Outside air temperature (check the sensor is fitted) Speed gong Average speed Average fuel consumption Still worth having, for the minimal extra cost and effort.
  13. Yes, your current instrument cluster will give you OBC if re-coded. You will still have the 7-segment OBC display, not the "dot matrix" display of models with factory OBC, but you will get the OBC functions. They will appear below the existing two lines. 7-segment: Dot Matrix
  14. The fans have a separate control unit, which feeds off the front control unit. Get a diagnostic check done, and it will probably tell you what is wrong. They are prone to stones jamming the fan blades, so it might be worth checking that first. Edit - just saw someone else suggested checking for stones in another thread which you replied to.
  15. Just to eliminate the passenger door window regulator, lower the window 2 or 3 inches from the top. Grab the window, and try to move it up and down. If it moves 1/2 inch or so, the regulator cables have slack in them, hence why it doesn't drop properly. A double honk means there is a fault in the alarm system. Use the Durametric to clear the codes, then lock and unlock it, and read any fault codes which come back.
  16. Yes, I think you would be best to get a diagnostic scan with a Porsche tester. Any good independent will have the equipment.
  17. I guess the problem could be with the microswitch which senses the key being turned to the lock position. I believe the convertible top will go up and the car will lock if the key is held in this position. It is odd that it happens randomly, and that the central locking button on the dash also won't work sometimes. I would have thought that a problem with the alarm control unit would more likely cause faults like that. Any dampness under the left hand seat (driver's side in the US)? That's where the alarm unit is located.
  18. The microswitch itself isn't available from Porsche. I think it is made by Burgess, but I'm not sure.
  19. The switch which senses if the door is open or closed is shown in the photo, with red and blue wires running to it: I'll wager it looks like this:
  20. It sounds like a microswitch within one of the door locks which senses if the door is open or closed is broken. The system 'thinks' the door is open, so after locking it immediately unlocks. As a temporary measure, you can use the emergency locking procedure. Turn the key in the door lock to the lock position and back 3 times in quick succession. It may also work if you press the remote button 3 times.
  21. Try looking in the input signals of the alarm control module on PIWIS. These are from PIWIS2 in Simulation Mode. Select Alarm from the Overview screen, then Maintenance repairs, and choose Input Signals.
  22. It is anyone's guess, I'm afraid. They used to release updates every two years or so, but these systems are up to 14 years old, so I guess they will stop supporting it at some point. The updates are seldom up to date anyway. If you put your DVD in a PC and check out the database file dates, they will likely be older than 2013.
  23. The latest USA map for PCM2.1 is indeed 997.044.904.51, which is mid-2015. Because you are running the 2013 map, your system must have been updated in the past, so the new map disk would be plug & play. PCM version 5024AD1 is software level B. You may also have read that there is a Level C update, which yours must have had. However, when you update from Level B to Level C, it only updates the Navigation Drive, not the PCM head unit. If you view the software version for Navigation, it should show Actual:00179436, which is Level C for the Navigation drive.
  24. It is possible that the Sport Chrono module has slipped into transit mode. It happens after a flat or disconnected battery, and can happen to various modules. If that's what has happened, it needs waking up by running the handover routine with a PIWIS tester.
