I recently sent in my Pro-78 for the rev C update and received a call from Whistler yesterday. They called because I sent a personal check to cover the $20 cost for the update. They will only take a credit card or money order I was told. Anyway, it was nice they called instead of shipping the RD back to me and making me sent it back with the requested form of payment.
The customer service girl was great, she told me that along with the Rev C update that I also will get a new receiver (I wonder what that entails?) and that my RD will "work really good now". I can't wait to get it back.
I also sent in my Passport 9500i for the ramp up prolem fix. I sent the 9500i the same time as the Pro-78. I wonder which one I will get back first???
