Update: [May 16, 2016] We have enough parts to make a dozen or so partial kits. We are completely out of the switches, so you'd have to rig your own. It may or may not look pretty (that's up to how clever you can be with the switch), but it would be functional. You would have to get a long 3-wire cable, a momentary switch of some sort, an LED [optional] and the appropriate connector (which I will provide the specifications for). If you're handy with that sort of thing, I may have a great deal for you! Let me know if you're interested.
IMPORTANT NOTICE: [January 25, 2016] It is with mixed emotion that I officially declare the Area 451 Cruise Control... discontinued. For sale since 2008, this fantastic product has seen diminished demand once smart clued in and made a factory cruise option starting in 2011 (I take pride in the fact I figured out 3 years sooner than they did that smart owners DO want cruise control!). The costs to produce smaller batches suitable for the lower demand would be far too expensive so it is time to call it quits. Congrats to Nicholas in Wyoming as the owner of the very last unit to leave the SmartieParts warehouse.
The most popular aftermarket product for the smart car, without a doubt! The Area 451 Cruise Control is the only unit truly designed from the ground up to work with the 451 (2007+) gas powered smart fortwo. Safety and reliability were the cornerstones of the engineering process and Area 451 hit their targets! It works great, is straight forward to install, and enjoys less than a 0.1% defect rate (outstanding for automotive electronics)! And it comes with a 2 year replacement warranty against all defects! Get better fuel consumption, less speeding tickets, more comfortable trips and higher resale value by installing cruise control on your smart fortwo!
Very detailed step-by-step Installation instructions are found at the Area 451 Parts website. Installation requires very few tools and most people can perform the task themselves in 2 to 3 hours. We encourage you to review the instructions carefully and visualize yourself performing the steps.
This cruise control is designed and tested to work in all markets on the 2007 - 2015 gas powered smart cars only (including the MHD model). It is not designed for, and will not work with, diesel or electric powered smarts of any generation. or any smart cars manufactured prior to 2007.
