Help with choosing the right update to Navigation DVD

[laphones00]

Hi,

I searched through the forum and couldn't find the answer to my

I bought a used 2006 camry hybrid with navigation disc: 86271-53020 which matches ToyotaDIY. (car is in California)

I am looking for an updated disc on ebay/craigslist/online stores but don't know which one to get. I am not sure if I need Gen4 or Gen5. It seems that 2006 year overlaps both?

Which one do I need for this car? And do I just swap out the old disc for the new one, or do I need to do something else?

Thank you for your help!

I'd get the one for the Gen5. Your best off asking a Toyota dealer for specifics.
