Does anybody know how to override the SRX navigation destination data entry? I can't type in destination information once the car is going over 5mph. When we are on a trip, I want the passenger to be able to look up destinations or enter addresses, without using the cumbersome voice entry method, which doesn't work at all well with general destinations, like specific searches for hotels, restaurants, etc.. A GM exec told me somebody online had a method around this, but he wouldn't tell me what it was. My Excursion nav system had a simple orange wire that had to be grounded in order to by-pass the lock-out.
