Sat nav retroactive installation

[MimiOB]

Hi, I bought my 2017 Toyota verso a few months ago. The dealer said sat nav was included, yet it said "unavailable" when pressing the function key. 

They said that it's not installed and that I'd have to take it to Toyota and see if they can install it otherwise they'd give me a new sat nav to have instead. I'd prefer the inbuilt type. Is it possible? Or shall I just take the removable type? Thanks.

The sat nav function was an additional module (Go module) with additional aerial that fitted onto the Touch 2 multimedia unit. To fit a new one would be quite expensive. Map updates are expensive.

If they supply a good quality (Garmin, TomTom, etc) stand alone sat nav, it may come with lifetime updates (lifetime of the unit in the view of the manufacturer), and would probably be more accurate. Be cheaper for the dealer as well.

Think overall I would plump for their offer of a stand alone sat nav provided it was a decent make, had lifetime updates, and had a reasonable size screen (5 or 6 inches).

Point for negotiation I would think.
