I will say that there was a "virginity effect" on mine. It was quite difficult to pop the cable off the terminal on mine even after I had fully loosened the nut, set up some mood lighting in the garage, and had Barry White playing on the garage radio; yes... despite all that, I had to pry it off.

However, after that first time the terminal and cable has always slipped in and out with no pain.

I ask because after updating my Navteq maps, my Uconnect system is locked up. I don't even know if the updates worked. It only shows "updating maps". I've removed the update disc after letting them be read for several hours. Very frustrating.

This will be the first time I've disconnected the battery cable.

If you are only disconnecting for the radio, a minute should be fine.
The whole transmission reset thing was a farce IMHO.

I would try a factory reset on the Radio and/or force a Soft Reboot.

Search the Audio forum on which buttons to hit.

Re: How long should the negative cable be disconnected

I did remove the radio fuse(30 amp-green) and that didn't free up the nav screen.

Finally bit the bullet and let the engine idle for 2 hours so the update could reread and finish completely. What a hassle. I sat in the seat and monitored the coolant temperature. Read 224 until I turned on the air conditioner which dropped the temp to 204 and it stayed there for the 2 hours.

FYI...
The 'idle for 2 hours thing' is only because then their techs can walk away from the vehicle and not monitor it.

If you have the push button start, you can set a timer for 25 minutes, set the Jeep to the RUN settings (2 pushes of the button without stepping on the brake) and then start your timer and then the update. Come back when the timer goes off and wait for the Jeep to shut down and then immediately go back to the RUN position (usually right around the 30 minute mark). The radio will keep 'power' for a brief period even if the radio display shuts down allowing you to reset the RUN condition. Just keep resetting your timer for 25 minutes to ensure you come back in time to reset the RUN condition until the update is donw.

Re: How long should the negative cable be disconnected

Have only driven it for about an hour since the update but I see NO Improvement. The screen is not a "touch" screen, it's still a "touch, touch, touch" screen. Using Voice isn't any better. It did not recognize "Walmart" and there are two nearby.

Haven't tested the POI database but I'm doubtful. So far, this has been a waste of $$$ and time though being retired, I have plenty of that.
