We bought our 08 jk sahara in March and as soon as we got it home we realized the uconnect did not work. Turns out for whatever reason there is no microphone. So I did some searching and found out that all you need to buy is a microphone to get the uconnect to work.
So I purchased the microphone, and had it installed in about 30 mins. I couldnt belive how easy it was.
In order for the radio to recognize your voice you will need to go into the diagnostic menu to activate the voice recognition. Do this by pressing the menu and both seek keys at the same time. Scroll down to page 5 and the last option is for the voice recognition.
After the voice recognition is enabled its just a matter of pulling the radio out and plugging the mic into the back of the radio. Once its plugged in, just put everything back togethet and your good to go. I decided to mount the mike just to the left of the radio on the dash.
Best part is there was no need to go to the dealer for any kind of system update or activation. Once everything was put back together, I was able to pair my phone to the uconnect and make calls. It was that easy! Btw I have the RER radio with nav. Let me know if you have any questions.
I ordered the mic from justforjeeps.com, do a search for mopar uconnect microphone and the part should come up. I can post the part number when I get home later tonight. There is no need for any rescan or update from the dealer. The uconnect module is built into the radio. All you need to do is plug in the mic and go to the diagnostic menu by hitting both seek buttons and the menu button, and enable voice recognition. It took less than an hour to do everything. You can even change the radio station with your voice once its hooked up.
