According to the manual for my Prius, the contacts from a paired BT device, including an iPhone or iPad, should appear under the "Phonebook" tab in the car's navigation system, with entries containing addresses enabled for selection as destinations. This much works as expected with my (successfully paired) iPhone 4S running iOS 5.1. But none of these entries work as destinations: selecting any of them results in an error stating that the address is "not navigable".

Is iOS 5.1 capable of sharing "navigable" address information from the address book over Bluetooth? If so, is this a known bug with either iOS 5.1 or the Toyota navigation system pairs with an iPhone?

BT Phone/Address systems use different Bluetooth "Stacks" or APIs. You have to check compatibility for each one at the mobile vendor's site or through third party enthusiast sites. Sadly, this level of detail is often beyond your average auto parts department because as an extension of sales they will simply say, "Yah, sure. It's Bluetooth, it'll work." For example our 2005 Prius could not speak Apple Address Bluetooth, but our 2012 Chrysler can.

Sadly, you won't get much milage (pardon the pun) out of hacks and jailbreaks because it comes down to the low level Bluetooth (sometimes at the chip level) that the equipment uses.

Also, to be an iOS compatible BT device, the device has to go thru the process of MFI certification.

So, again. you'll have to call your auto support line and in the case of the Prius; prepare for disappointment.

In the case where you have been able to exchange address book entries, you will likely need to make sure that the address book entry is in the right format. (Country, state, label, etc) Again... check with expert forums on that.

In the case of a Prius, I stongly recommend: PriusChat

No, they do not. The Prius navigation system requires a very specific format for addresses which many users are unlikely to have chosen, and most are likely to have violated in at least some addresses.

In order to have a chance at getting the contacts from your iPhone to be "navigable", you'll need to check them all and edit each of them to change any entries with terms like "Drive", "Street", "Avenue" or "East", "West" etc. to the corresponding abbreviations (DR, ST, AVE; E, W, etc.).

  • For the Entune nav system for later Prius that is a fix. As I mentioned, I had a 2005 with a different nav system with a different BT stack.

  • @AndreiFreeman: Yes, understood. My "No, they do not" is in response to the original question, not your answer, which is also correct.
