Hey, hope you can help!

I bought an OEM VW Navi and got it fitted to my Mk IV TDi Golf. It works fine with my OEM CD Changer, and I get maps through ok (got an original '05 Map CD in it. It knows where it is by updating though the GPS Antenna and I usually get 6-7 Satellites at a time.

Also when I set it off to direct me somewhere, I can get a nice hilighted route on the screen, and a nice voice telling me that it's calculated the route, but it simply won't direct me there! Also it is very slow in updating my location (maybe every 2 minutes?).

Basically as far as I can see the Navi is trying to do all the work through the GPS Antenna and is not picking up a Gala or Speed Sense signal through the car. The red switch on the cable loom has been tried on both settings to no avail.

The place that fitted the Navi for me (good local Auto Electical place) has tested the car again, and says that there is no signal coming through from the car. They say that it's possible the car was never fitted with this. I was under the impression all Mk IV's had this fitted? Can someone confirm?

The garage says that there's a cable, or at least the bits listed in one of their suppliers catalogues - they are going to find out a cost and what's required to get this running. But basically I'm not looking to spend any more money just to get this running and would like it clarified as to who is possibly talking rubbish, or indeed what is wrong.

Sorry for the long post!!

on the mkiv golf mate all of them im sure, there is a gala connection on the stereo ios connector

mine on the r32 was blue/white.

so its deffo there.

check on yours, look at the factory HU and look at the sticker on
there, it states which pin is GALA. so u know where your looking on the
iso con

Cheers, I'll check out the Original Headunit and see what it has labeled.

I can't get at the ISO Loom though because I don't have the tools/keys
needed to take the Navi Headunit out. I need to go back to the garage
to get that done.

As long as it's pretty much confirmed that the Speed Pulse is already
wired up in all Mk IV's then i'm happy - saves me shelling out for
something I don't need.

Alternatively if anyone has experience installing this Head Unit as an aftermarked install, would they be so kind as to help?

Cheers

As far as I know the gala sensor is part of the abs system, so if you have abs, you have a gala sensor. Sounds like the cable isn't working or it isn't correctly seated (its quite tight behind there so worth a look to see if anything has come out). As for getting the Navi unit out, I just use 4 small kitchen knives in each of the slots. An old credit/debit card also works. Takes 20 seconds!

 

[aberdeentdi]

Sounds like you may need the Plug and Play adapter for the Head Unit,
I've recently installed the MFD in mine, and it needs the P+P adapter,
as there are two GALA connections on the back of the MFD. Does the
volume go up and down at the moment dependent on speed? If so GALA is
working fine, just the connection to the GPS part is not hooked up,
this is where the P+P Adaptor comes in. You can pick one up on Ebay for
around ?15.

 

[Abe.TDI]

I have ABS. As for removing the headunit, I tried the smallest knives I have in the kitchen but I was only going to scratch the Headunit

 

[Abe.TDI]

I got a P&P Adapter with the Headunit - if by that you mean the one that goes between the ISO Connector in the bottom right corner, and the 20-pin connection in the upper left (looking from the back), it also has a Switch on it - and this has apparently been tried on both settings.

 

[Abe.TDI]

Right that's it, I've exhausted every line of enquiry in getting this thing working and i'm at the end of the road.

The CanBus interface is fine, Speed Pulse is fine, It picks up 6-7
Satellites at anytime and knows where it is. It just doesn't update
fast enough. I've just been forced to go to the Dealers with the car
finally and they won't touch it because of the P&P Cable but have
confirmed the headunit itself is working perfectly well.

They said "Checked for Sat Nav slot to update, found wrong sat nav
pickup for unit, removed unit to test wiring, found home made loom,
will require a proper antenna and wiring to get unit to operate
correctly and efficiently". They've also priced this at a cost of
?73.70 ex VAT for a "Base", ?145.00 ex VAT for a "Kit" and three hours
labour at ?50.00 ex VAT Per Hour - total cost ?429.70 inc VAT. The
technician I spoke to guaranteed me the headunit would work fine when
this was done (or after the money was in their pockets...)

I'm ready to throw the headunit out and stick my Beta Headunit back in, this is too much of a headache.

Is there anyone in the Central Belt of Scotland that would be able to
look at this? Any companies at all? Gosh, even the North of England?

Hi mate,

Assuming that you have the correct plug and play lead installed and you are picking up good sat signals, i would try the following:

Go into nav menu settings 'volume' and turn the GALA volume uo to max, go for a drive and check that the radio/cd volume rises with road speed (by turning the volume to max you notice the change in volume far easier), when you are happy that the GALA disable switch is in the correct position and you are receiving a GALA signal, go.......

Into the nav menu again and find the 'pulse settings' menu, this needs to be set to 8 to allow the GALA to update the MFD correctly, then go for a drive for around 10mins or so to allow the unit to calibrate and hopefully job done! []

I had the same problem as yourself with mine (my pulse setting was set to 45 as the MFD came out of a german spec car which use ABS pulse inputs as opposed to GALA inputs on uk cars), the above procedure sorted mine out mate, so give it a go..

Hi Steve, thanks for replying.

The GALA Volume test has been done to death and doesn't make any difference at all

The car is 100% set for 8 in the Pulse Settings menu. I'm going to set it for 45 instead just now before i head to a friends house (that'll be a 20 mile round trip) just to close off that avenue of thought. Will let you know my findings.

 

[Beddie]

No probs mate, hope you get it sorted as it's a really nice and handy bit of kit when it's working ok! []

Noticed you mentioned you had a Beta head unit in the car originally?, it got me wondering whether there is a compatability issue with the P&P loom which is always mentioned as being used with a Gamma...does the GALA pulse on the BETA loom come in on a different pin to the GAMMA, if so, the link to the GALA pulse for the navi may be dead?

Think you may be best off removing the unit and checking all the plugs are in correctly as the wires are a VERY tight fit when the unit is in place, maybe the 26pin connector is not seated properly and the GALA signal to the navi signal is not being received?

Have you tried posting for some help on www.vwnavi.com...

beta is compatible, i had sat nav installed in my V reg 1.4s !!

Mate where did you get the sat nav from? It is NOT uncommon for looms from foreign sellers to be incorrectly wired! Unfortunately i'm too far away in scotland to check for you (I live between Aberdeen and Inverness) but if you send up the loom i can check connections for you? If you can't get the HU out i have nav removal keys i can send to you for a paypal deposit that will be refunded when they are returned. If there is not a problem with the MFD then it is definately a wiring problem. If you want to have a go yourself here is a diagram i made a while ago with correct info.

Check pin no.5 on the 26pin connector with a multimeter, the voltage should increase with revs/speed. If it does not try the gala connection on the actual iso block, if this doesn't show any voltage then your gala connection is dead. It can be picked up from the cluster though if this is the case.

If it does and the other pins are fine too then it is a speed pulse problem. Try 43, 45 or 8.

Please let me know how this goes, I love problem solving!!

 

[thechief]

By the way mate is it a veersion A,B,C, D or G? Please remember only versions D and G can use plug and play adapter.. Versions A,B and C are a bit more involved and you have to hook up wires to ABS L and ABS R connections. If you can't get the unit out scan it with vag-com to get the part no.

Hi Mate,

Thanks for your detailed replies. I can confirm it was a Gamma headunit
in my car originally. Ive been driving other cars and staring at the
Beta logo's - that's what's put me off.

Will Halfords have the Keys I need? I will check them tonight. I came
down from Stirling yesterday morning and ran it on Speed Pulse 8 &
45 but apart from it speeding up as I went through Glasgow in the rush
hour (maybe updating every minute or so?). I will stick it on 43 before
leaving work today just to try that.

I bought the headunit thinking it was a "D" but I am suspecting it's a
"C" unit which if I understand will not work with DX Enabled CD's? The
only CD's I have here are DX enabled. Do you think it's worthwhile
buying a Non-DX CD and seeing if that does anything?

If Halfords don't have the keys I need tonight then I may just take up
your offer thechief and talk to you about taking a look at the cable
etc.

Cheers

I am 99% sure this is a speed pulse problem. Either wiring or programming. Version c, D and G should be fine vwith an adapter loom. Version A & B will require a more thorough install. They also do not recalculate your route if you miss a turn off. Versions C,D and G 'have' MFD written beside the cd slot. If it has this assuming it has not had a new faceplate at anytime it should be plug n play compatible. Vagparts can do the proper removal keys. I've forgotton whether C D & G use dx or non dx so have a search about on www.vwnavi.com I always get them mixed up so cant say for sure!!

Just found this:

Golf 43 for ABS 8 for GALA, someone in america said 45 worked better for them.

Your adapter may be wired up using abs/l and abs/r connected to the gala signal so try out 43.

 

[Abe.TDI]

it has MFD written on it for sure.

Are the C, D & G versions compatible with DX CD's?
Are the C, D & G's incompatible with DX CD's? I have DX CD's just now but would
buying a non-DX CD be beneficial?<o></o>

 

[Abe.TDI]

Ok i'll try 43 at 5 when I leave work, will take the car on a jaunt up
to Halfords anyway for a wander round and a few extra miles of driving
for calibrating the car.

 

[thechief]

Is your car showing  route on the map? An outlined line? If it is your cd will be working fine. If you can imagine being your nav unit it cannot tell the car has started moving as it is not picking up a GALA signal. When you see the car slowly moving on the map this is it updating from the GPS which updaters every 20s to a minute i believe. You need to check out pin 5 on your 26pin connector to see if there is a voltage coming through it or else you are wasting time changing speed pulses. Hope that helps?

Right "43" doesnt make a difference. That's 8, 43 and 45 tried.

Halfords didnt have the tools I need. The Headunit does show a route on the map.

Can you PM me regarding sending the tools down like you previously mentioned?

Cheers

Where is your GPS sensor mounted? These can be very s elective if mounted near metal or magnetic sources. I have mine on top of my dash behind my tax disc, but i have a Becker Traffic Pro and it works superbly.

Just a thought.
