Hello, because I have not found any concrete contributions on the topic of Tempomat here or in other 500 forums, I would like to start here. Maybe someone has already successfully retrofitted and can give tips. Starting point: Fiat 500 69 PS (EZ: 29.12.2015 – Modell 2016) No Tempomat, no Limiter In various Fiat forums you can find one or other report, that with existing limiter the steering pole switch has to be changed and you have also the Tempomaten. Another report says that the cable for the steering pole switch was already available and only by installation / plugs the Tempomat function could be retrofitted. With eBay now for ~40,00 EUR a lever has been fired, one can try it out. Of course, with our 500er no plug is prepared. Now the question arises, how much effort (time/cost) the installation actually means, without at the Fiat-Stock-Stick a small fortune to burn it. I leave this here at times so. Evtl. has actually got some tips. Craft skills and technical understanding would be given. Otherwise I would like to contact the assembly unit.
