I just received my new TST 507RV kit today... Ordered it online for free shipping and 2 year warrenty for the month of December. I opened it up and noticed that the Suction Cup was not part of the order. When I ordered it, the TST web page said the 507 kit comes with this SC, but in the set-up manual that came in the kit stated that the SC is "optional". So my question is, did yours originally come with the suction cup? I just tried to call them and they are already closed for today.
