Cannot Connect to 2011 Chevrolet Traverse Bluetooth System iPhone 4S

Did you read the User Manual for your Traverse Bluetooth system?  Have you placed your car's bluetooth in discoverable mode?

Yep, had the iPhone Bluetooth onA and showed as discoverable.  Activated the Bluetooth in the car and told it to pair.  By all of the instructions I should see "Your Vehicle" on the iPhone but I am not.  Even the sales guy was puzzled.

Reading this forum it seems like since iOS5 came out people are having problem with the Bluetooth functionality.  Unfortunately Apple says it is not them and the car makers say it is not them.  Only one who gets hosed is the buyer.

I have a 2011 Chev Avalanche LS; was able to pair my iPhone 4 and then the iPhone 4S without any issues; worked great. (Yes, unfortunately past tense!)

A couple weeks ago, all of a sudden it started acting up on me.  The handsfree wouldn't work - it started with a call coming through the iPhone only.  I couldn't get iPhone to put the call through the vehicle's system.  "General Motors" selection was available, but wasn't clickable.

I had already had a battery problem with the iPhone 4S and was having it replaced.  New replacement iPhone 4S arrived a few days ago.  Tried to pair it to Avalanche's Bluetooth.  iPhone won't discover Avalanche's Bluetooth.

Tried connection with Blackberry Bluetooth earphone device - iPhone wouldn't discover it.

Tried to pair Motorola cellphone to Avalanches' Bluetooth - discovered once, but Motorola phone wouldn't allow input of 'passkey', so it didn't pair with Avalanche's Bluetooth.  After that close connection, the Motorola wouldn't discover the Avalanche's Bluetooth.

The original iPhone 4S had the latest IOS 5.1.1 installed and worked great - but, it was paired back in Nov 2011, so the iOS would have been a earlier version.

Apple has offered to replace the replacement, though.

But, if we don't know where the problem is - then, I'll probably have the same issue with the new New Replacement!!!

I'll keep you posted!
