CMAX SEL (Full Boat) I took this dude in Aug. 2 for the 3.5 udate (from 3.1.3) and the liftgate software update. The dealer started the orgy about noon Friday and called me to pickup late this afternoon, Aug.. 5. I'm led to believe two techs spent the better part of 12 hours at the car and on the cellphone. OH - WOW I got it back with the tailgate in good working order, V 3.6.2 installed, and last, but not least, the MPG software installed. I have had the opportunity to do some data entry in the NAV system and my initial impression is vary favorable. Easier data entry; better, more reliable voice recognition. Maps are updated and more info is displayed. I can now read the outside temp. I am not to sure what to make of the POWERFLOW screen, but it is a conversation piece. Over the next week or two I plan to collect data to evaluate the new MPG software. I needed mpg help in the winter and that season is 5 months in the furure. P.S. Aug. 6 Phone paired and phone book downloaded - slick! All NAV addresses reentered BY VOICE - never able to use voice with 3.1 - always got tangled up in my shorts. Presets for the radio/SAT all OK after the installation of 3.6. I suggest a quick tour of the sound, voice level, and other vehicle parameters. Many of mine returned to default. Also found the "DST ON" button missing for the clock. So far, no anomalies, blue screens, or unexpected shut downs. This technology is now a pleasure to use. I am no longer a slave to the software, it now seems to be helping me.
