LG

I have a LG Wine UX280 Red and a 2010 Ford Fusion with MS Sync. I successfully paired the devices and it works for a few days then stops. Both devices still list the paired partner, but will not reconnect when this starts to happen. I also have a Blackberry 8330 and it always works with the Sync. I have removed the 8330 to make sure it's not conflicting with the UX280. If I completely wipe the BT config on both the Ford and the phone, I can re-pair and it works again for a few days.

Software upgrade for the UX280 perhaps?

Having both the 8330 and the Wine Paired at the same time shouldn't be an issue, but that was a good step to troubleshoot. Once the Pairing between the Fusion and the Wine is broken, can you easily"Re-Pair" them or do you really have to delete the devices before you Re-Pair?

The Compatibility Chart that I have from Ford looks to be a little dated so I'm not sure how up to date it is, but it isn't showing the Wine as being tested. You can check the list out at: http://www.syncmyride.com/Own/Modules/Intercepts/InterceptIOP.aspx
You can check with a Corporate US Cellular store to see if they have posted any updates for the Wine... Can you tall me what version of software is in your phone? You can usually find this info by going to the settings menu, then Phone Info, and it should be under the heading of "Version"... It's the last two end digits Something like "xxxxxV03" which would be version 3 of the current software.
