1.1.3 Update Doesn't Work with Garmin Nuvi

I just bought a Garmin nuvi 660 and updated the bluetooth firmware. My iPhone was already running the 1.1.3 update, so I started experiencing the 30-second disconnect problem immediately. I did "catch" the iPhone turning off Bluetooth, so it does seem that the problem lies with the iPhone update.

In any event, I seem to have resolved the problem by setting the iPhone's "AutoLock" feature to "Never" (in Settings | General). Yes, that means the display is on all of the time. Since the handsfree usage will be in my car, however, I can live with that temporarily as I can keep the iPhone plugged into a power source constantly.

Apple needs to perform soon!! Already been to see a genius! Yes he did a new phone restore and i synced and yes the garmin worked. For a while! (2 days) then it gradually went back to its old self. Connect then disconnect! I kept doing the restore to new phone and it would work for a short while then back to the same old stuff! Its been a month for me doing this and i give up! Thanks for taking my money Apple! Has anything new come out to address this that i am unaware of?

I also have the iPhone and the Garmin Nuvi 680.. the update to 1.1.3 really upset me.. I have noticed that if you do a total restore of all settings on the iPhone then connect it to iTunes and do it as a "New Phone" the iPhone & Garmin 680 WILL work, but only for 2 day or so. then it wacks out again! 😟 I have let the iPhone look for the Garmin. It seems to work better then if you let the Garmin look for the iPhone. I tried to go back down to my org 1.1.2 but I cant get it right. sigh Will someone please take the time to explain this to me step by step. I get as far as uploading the 1.1.2 to my phone on iTunes but then I get an error msg and then i get stupid 😟 Any help will be so greatly welcomed! Thanks all!

OK, confirmed cause and fix...

I don't post here much, but I have been testing this and can positively confirm a cause and a fix.

Of course, this is a little moot, because apparently 1.1.4 fixes this issue anyway, but I know many people with hacked phones will not be installing 1.1.4 for some time.

So, first the cause. The iPhone loses the Bluetooth connection because of a problem caused by an excess of calls in the recent calls log. Bluetooth devices, like the Garmins, request this log data. Usually a phone keeps only the last 10 dialed or missed calls. The iPhone keeps a much longer list and tries to send it all, overwhelming the receiving device, and the connection is disrupted. That's the cause.

So, the fix? Well it should be pretty obvious, and yet it really IS this simple. Go into your recent calls log and clear it. There is not step 2. That's it. Done. Fixed. Next time your device starts losing the connection again, just clear the recent calls log again.

Of course you won't it's this simple until you see for yourself. Go ahead. It works.

I also confirm that 1.1.4 fixed this problem with my Nuvi 660. Hooray!
