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.
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.

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
