It is
not usually necessary to fit electric servos to Fiats, Mercedes or VW's. We have
cruise control systems with vacuum servos.
Fiat:
Motorhomes
in the Fiat range built before the year 2000 will not have a speed signal. Any
model after that i.e. Fiat JTD models have a useable speed signal.
To keep costs down:
If
the motorhome is not a Fiat JTD then we recommend the GC50 with a speed pulse
generator instead of magnets.
If
the motorhome is a Fiat JTD then any cruise control in the professional series
will be suitable.
Mercedes:
If the Mercedes has a speed signal then we recommend the professional series
of cruise control.
Ford
Transit:
If
it has an electronic throttle it probably needs an electric servo.
