Hello Everyone...
I am Kyle Brehm the Wholesale Manager at the Southcenter Car Toys in Tukwila, Wa.
We have been selling and installing the Area 451 Cruise units for about a week now, and I would like to clarify the "Warranty" issue...
No, simply installing one of these units does not void your vehicles warranty.
However, if the unit/or the installation causes a failure to another component of the car, the manufacturer's warranty is void on the failed part.
We are able to guarantee our work for as long as you own your car, so we will take over where the manufacture warranty is void in the event there is problem with our installation.
If you need any further information, please let me know.
Kyle
