Speed Pulse on Mk1

I'm thinking of upgrading my stereo to a SatNav version.

It appears that for it to work correctly I need to make a connection to input the speed pulse.

Does anyone know if the Mark 1 F has this facility and, if so, where is the best place to access the wire?

Thanks.

I think you would need a Mk2 to get an electronic speed signal.:dunno:
Why would sat nav need this anyway?

It extrapolates your position based on your last known position and direction should you lose the satellite signals going through a tunnel etc.

The power steering must still get a speed signal, so I thought there must be a sender in the dash somewhere.

Dieters site shows a WB cable (White Black) and it says Mk1, but it looks supiciously like a MEMs3. http://www.mgfcar.de/schedules/sb14.jpg

Doesn't the ABS send a pulse?

I do know someone who used a bicycle speedo to generate a pulse for his emerald ECU on his T16 maestro, I think he mounted it on an inner hub or a drive shaft.

The Mk1 doesn't have ABS - I've got forearms like Arnold whatshisname

Some Mk1's do have ABS, it was an optional extra

My Mk1 has ABS..... The pulse from the speedo for the PAS comes from a reed switch in the back of the speedo operated by the cable turning I seem to think.... As the PAS switches off after a few minutes when the speedo cable snaps.

ABS is a braking system.
PAS is power steering.
EPAS is Electronic Power Assisted Steering.:yesnod:

Well I don't think I have either ABS or PAS on my '97 Mk 1

Whats this 'reed' thing then?

Beryl my Mk1 has both ABS and PAS, but as I said they where optional extras..

The Reed jobby, I am not sure about sorry

Ok. I think my Tomtom seems to do that anyway.:dunno;
