I started trying it but did not complete my analysis yet.
The current main problems are:
- Instant Nav has Quadlock connection, Standard MP3 Radio has ISO -> Adapter needed
- Some sources say that a additional connection wire from the body computer to the instant nav is required which is not already fitted within the standard wires. I could not verify this yet as I do not have a connection diagram for the Instant Nav.
- Dont know if the Blue & Me works with the Instant Nav as there are different spare part numbers of an Blue&Me with and without Instant Nav
Please consider installing an after market unit (especially if you are not having Blue&Me already installed in your vehicle) as these are most better than ther Instant Nav. I already had a look on some videos on youtube and afterwards was very dissapointed of the look and feel and the "features" of such an new navigation system. The only advantage is the integration in the car. Navigation and menus are really oldschool, unfortunately
There are a lot of "China Navs" available for your Fiat Bravo which 100% fit in the car and you can continue using your Blue & Me, steering control, etc.
