Using Android contact for Navigation

Octavia Mk3 with Amundsen satnav.

I have two phones - a Windows 10 from work and a personal Android running pure Oreo with Android contacts app.

Both phones have trouble navigating to a contact's address and I'm getting fed up of "This contact has no address that can be used for navigation" . 

I can usually manage to get the Win10 phone by ensuring the street address is in correct field and putting the city in both the City and State fields on my phone.

The Android is useless as it doesn't parse the address into separate fields, it's all dumped in a single line.

As it's company car the Android Auto update isn't a goer - anyone have any better success?
