Thank you all so much for your time and information. I will set up an appointment with my dealer to discuss his current model. It is a T4. The new one sounds great, but at this time we really don't need the intercom feature. But, I was wondering, when you mention the cost of the unit, is that $1,800.00 dollars (US)?
Again, thank you for taking the time out of your busy day to answer my questions.
