Update. With budget and other matters in mind, I bought an Escort Solo S3 cordless unit from Crutchfield, skipping the GPS feature. Determined that our new car doesn't have live internet connection, and of course neither does the 2011 GTS. Just got back from a 2496 hundred mile RT drive using our '11 GTS and covering the miles in 3 driving days; Oceanside to Gig Harbor WA and back. My advice to you: do NOT try this without adult supervision!!
I did NOT speed...ran no more than 2-3 or 5 to 8-9 miles over the posted limit, if that much.
12 + 6+ driving up (overnight in Medford OR). Return trip: 20 hours straight. Most detector alerts were from road warning signs and auto door openers at gas stations. Several times the alert did, in fact, wake me up and sure enough I came upon a smokey unit parked along the highway. This was all looking forward. Not sure how much alert I'd get from a following smokey. Likely the window tint on the rear glass (added by some previous owner) might have minimized the effectiveness of the unit. ??
Bought the cordless because later this week we're off to Virginia in our Macan S. Want to move the unit for use in any/all of our cars. Battery indicator tells me I used 1/2 the battery power in what was about 40 hours of unit-on time. Reading screen of this unit is very small. Otherwise, seems to work OK. Oh: 28 - 31 mpg during the trip; lots of stop/go sections: Salem, Portland, Tacoma, not to mention LA work traffic. Two plus hours to clean the bugs off the car and spiff up the wheels. GTS turned over 42,000 miles coming home. No garage queens around our house.
Thanks for the info, Lucky Dave. I'm sure other chapter members will find it as interesting and useful as I did.
