Windscreen Replacement & GPS

[ralphmusic]

Returning from the FoS my SatNav couldn't get out of its mind that I was circling Chichester. Visited Exeter OPC yesterday where they found the GPS sensor was not connected. Culprit being the OPC recommended windscreen replacement service that did not reconnect the sensor when replacing the windscreen some time ago. Apparently the SatNav continues to work without the sensor for some time (presumably on dead reckoning) until it runs out of memory.

Anyway, if you have a replacement windscreen, best to remind fitter about the GPS sensor... luckily someone with small hands can reconnect without having to remove scuttle cover or windscreen.

Sadly you're not the first to have had this happen.. I've read of quite a few owners whether done via OPC or not where the connector hasn't been reconnected.
Glad a small pair of hands fixed it though!!
I'm looking at a new screen shortly, so it's one of my concerns for sure.

FoS was good I thought, was there yesterday and was in the 1912 Sunbeam up the hill in the morning, so had Sterling Moss behind us in our group and met plenty of famous drivers there too in the changing room, Jensen B, Jochen Mass and Jackie Stewart so very lucky.

Like your white Carrera as I have a white turbo......

I guess we all want to know how one can get to drive an exhibition car up the hill...

The nearest I got to a famous driver was Richard Attwood finding a pen for me on Thursday so I could sign my indemnity form..

I met Nick Heidfeld at the FOS yesterday at the Skoda Motor Sport rally area. My daughter who works for Skoda Motor sport was manning their rally area for the 4 days so introduced me to him. Nick ventured up to see Skoda's current rally cars (cant think why !! []) understandably Skoda grabbed him and Juno Hanniken took him for a blat around the rally stage at the top the hill ........... Well done Skoda, got loads of media guys up there when Nick turned up ...... Tried to grab a passenger seat drive with Andrea Mikkelsen, said he was busy[][] ........ perhaps wearing my PCGB jacket at the time didn't help !!![]

Crikey - didn't take long for this thread to get off topic!![]

sorry boss got excited about Nick !!!! []............To bring it back on topic ........... I had a windscreen replaced a couple of years back. Not only did they (AutoGlass) forget to reconnect the Satnav, they also forgot reconnect the radio antenna, broke the passenger sunvisor, get black mastic everywhere and took 2 days putting it all right !!!! never ever again ..............[]

getting back on topic for a second (I had to forgo some free tickets to the FOS as I was away travelling with work, so it's a sore topic) - ralphmusic: do you have any pictures of the GPS sensor or can you describe it in a bit more detail? Mine is broken, and needs replaced. Replacement unit is only 60 quid, but OPC want to charge me 140 for fitting it. I can't imagine it's hard to do yourself - having re-attached the cable to it, what's your opinion?
Cheers,
John

This link may help albeit from a Cayman navigation install. Nav Install (the GPS aerial is midway down the article.)

The GPS aerial sits above the pollen filter.

btw are you sure it's the aerial that is at fault as it maybe the aerial cable that needs connecting or replacing?

Hi Guys,

My 997 S2 Carrera needs a new screen and my insurers want to use National windscreens and they can't guarantee they will use a genuine Porsche replacement. Are there pattern screens out there or are there only genuine Porsche OE?

Also, if they havn't replaced 911 screens before, what should I make them aware of please?

Never heard of he GPS sensor, where abouts is this in relation to the car please and is there anything else they would need to connect?

Many thanks.

Barry.

When my screen was replaced, the fitting company (recommended by Exeter OPC) offered me OEM or Saint Gobain screen - they said the only difference was the Porsche logo on the former. The screen fitter (although he forgot the GPS sensor) taped the screen down on the top two corners after fitting so that the adhesive could dry whilst the top of the screen was pressed (gently) in place - he said that this was their way of doing the equivalent of the factory manufacturing process. I happened to go on vacation the day after fitting so it sat in the garage for 5 weeks with the tape in place - it does not need 5 weeks to dry though!

As to the position of the GPS sensor, see Nick_USA post above.

PS tape referred to above - he made up two "sausages" with tape and then placed one at the top corners on the glass and held them in place with tape running tightly on the top windscreen rail and over the "sausage" and to the screen - hope that is understandable!

Having seen the screen fitting robot in the factory get adhesive all over the place and scrap several screens in the process I'm not sure that aiming to emulate the factory process is a recommendation!!

Barry, the screen has the GPS aerial built into it- the thin lines you can see and is connected at the base of the screen via a cable to the GPS unit behind the dash.
It is very much the link to the aerials being described here..

Not so Gary the aerials you refer to in the screen are the main aerial (centre) and the diversity aerials (left and right) the GPS aerial is the square aerial under the plastic cowl.

thanks for the link Nick_USA. Perfect. gives me a job to do this weekend (assuming I can find a long enough break in the rain).
Will double check it's not a simple cable re-connection first. However, as I happened to pass the Reading OPC a month or so ago, I went in to ask about the broken sat-nav, and the engineer looked at it for about 20 mins and came back saying the GPS sensor had gone. I presume he knew what he was doing and checked that it was "plugged in" - you never know though.
Should the GPS sensor need replaced, does anybody know if the generic 10 quid units on eBay will work? I presume it's a fairly standard component...

Theoretically yes but practically no as the cable that runs from the GPS to the PCM has a keyed plug at both ends so that you cannot wrongly connect the cable to something else.

A new GPS aerial is around £60 after club discount. Prior to removing the wipers/plastic cowl etc you maybe able to remove the plug and slave in the new one to test it; assuming you have small hands and some patience.

Edit: The OPC may have tested for a GPS signal but may not have checked to see if the plug was on, it isn't obvious.

The module under the scuttle is a fairly easy job.

You will need: a 13mm socket (preferably on a wobbly extension to get to the O/S wiper arm) a 10mm socket; a T25 torx and a panel clip tool (or pig/crows foot) <--- this is for two plastic rivets behind the battery (a spray of water over them helps to release).

With the wiper arms, scuttle screws and nuts removed, the scuttle still won't lift up enough owing to the cable still being attached to the module. I find a stubby screwdriver is best for this (two screws for the metal plate and then one for the module).

Of course, if you're just reconnecting the cable, you can just about do it (carefully, being so close to the screen!). Use a small mirror to help you see what you're doing.
