Somewhere in my house I have a GT10 transmitter- can't find it. My original GT10 (receiver) is sitting here. I ordered a GT10SII (the complete unit) since I need to use it immediately. Will the GT10TII work with my old GT10 unit? If it does I'd save $99 and have 2 units. If is does, can 2 units be used at the same time without conflicts?
Thanks for your help.
