Recently had my windshield replaced (that nightmare is another subject) and when I got the car back several months later the battery was a bit weak. I always keep it on a CTEK but it is a 2015 that stays in storage quite a bit with only 13K miles since new. So I replaced the battery- easy in/out 10 minute swap.

Now the fun stuff. My SRT pages do not work anymore- says I need to start a subscription to uconnect or some junk and then says my link to uconnect doesn't work. In addition if I sync the clock to GPS it is several hours off. Now for the real cool part. Using my NAV this weekend it rarely showed me on the correct road. When the highway was the only thing for miles it threw me there, but then would show me out in the middle of no where and try to recalculate.
I've done a soft reset by holding down the two knob buttons- have done that 6 times over the past three days.

So question is, By replacing the battery did it jack something up that is a simple update at the dealer? This couldn't be caused by the windshield replacement could it? To my knowledge the GPS antenna is in the rear hatch not the front windshield electronics cluster.

Thanks in advance for the advise and opinions.
