SVB delivers a Tiller Pilot Drive without manual and without installation instructions. SVB then does not respond to questions about this. SVB is obviously just a dozen schuiver and does not provide any support. The Raymarine EVO-100 is probably good, but you should not buy it at SVB.
Unfortunately, the system was already delivered defective. Although the error could be found quickly by telephone consultation but then I had to send the part back to SVB and wait for a replacement. That took almost two. The delivered parts were then unfortunately not complete and again faulty. After many phone calls with the very nice and competent people of Raymarine Germany, the flaw in the software could be found, but that cost me almost four hours of work. Unfortunately, I was not allowed to use Raymarine's highly praised 24-hour onboard warranty, as I had installed the system myself.
The white antenna/compass part looks like a toy; a small plastic tab broke off and the top part flew off. Now I have to figure out how to find a replacement. It's unbelievable that for the price of this product, the finish isn't more robust, in keeping with the marine environment it's supposedly designed for. Very disappointed.
