Hello FacciaBrut,
Thanks for posting in the Apple Support Communities.
It sounds like you've noticed a contact address isn't returning the correct results when you tap it to get directions, right?
If we have that correct, let's first check that you have the latest iOS version installed on your device. If an update is available, be sure to complete a backup of your device before installing the update. For assistance with backing up or updating, check out this resource: Update your iPhone or iPad - Apple Support
If you have the latest iOS version installed on your iPhone, check that the address entered matches what is shown when you search in the Maps app. If the address is saved differently in the contact, that could be why you're seeing this occur. For assistance with editing a contact on your iPhone, check out the steps below. These steps can also be locate here: Edit contacts on iPhone - Apple Support
In the Contacts app
, assign a photo to a contact, add a pronunciation, change a label, add a birthday, and more to your contacts.
1. Tap a contact, then tap Edit.
2. Enter or update their contact information.
3. When you’re finished, tap Done.
We hope that's able to help. If not, provide more details on if this occurs with all contacts, or specific contacts. In addition, let us know which iOS version you're using and provide any additional details that could be helpful. We'll use this information to gain a better understanding to provide you with the best next steps to take.
Have a great day!
