Navigation / Headunit Conflict?
Hi all,
I'm looking to upgrade the headunit on my GX470 which has the navatigation system pre-installed. I've taken my car to a local car audio shop and they told me I can't upgrade my headunit because it will create a conflict with the navigation.
I find this all to hard to believe that this can't be done and still have the navigation system working properly. I'm aware that the OEM headunit and Navi are intergrated and can function the radio via the touchscreen (which I don't really care about). But the idea of the Navigation system not working properly is not what I want to happen.
Anyone with experience on this? What was the outcome of upgrading your radio and functionality lost on your Navi.
Thanks,

Head unit, nav, cd, dvd and any other toyota accessories work in a network, sort of like computers. They need to talk the same language (protocol), and they need to know each others capabilities. Some companies out there do develop specific products that work in toyota's network (vais, etc.). You would have to research it to find out if there is a head unit out there that would within toyota's network and interface with other components in your car. Otherwise replace both, the head unit and the navigation. Plenty of aftermarket products are available with built in video and nav capabilities.
