Avensis navigation unit error

[J Tam]

Hi everyone. Hope someone can help. Battery went in our 2011 avensis and an error has come up on the navigation unit stating to contact the dealer. Audio, bluetooth, rear camera etc does not work now. From reading previous blog, I need the sat nav DVD (which I don't have) for tns 510 model. I can't find any on eBay but there are plenty for tns 600 or tns 700. Would one of them work? 

Ibe also gone to https://www.toyota-mapupdates.eu/Home/ to order one but I'm not sure if its the disc or the sd card which is not what I need. 

 

Any help or guidance would be appreciated. Thank you

The TNS510 takes a SD card. Here's the details of how to check if you've got one already in your unit:
