If you buy the 451 navigation product, this is what you will get (obviously with the sat nav unit). The old sat nav unit was the Garmin C510, the new replacement has the same fitting but the Garmin sat nav is a widescreen unit. It is believed to be a Garmin 760.
On the left is the communications unit (smart part number A 451 820 01 51), this is the main hub
that everything attaches to. In the middle is the dock, this screws into the dash. On the right is
the auxillary input for connecting your MP3 player. You may not get this cable with your kit.
The communication unit has 4 connections.
A - MP3/auxillary input.
B - Main connector.
C - Sat Nav connector.
D - Bluetooth phone connection.
Remove the stereo, info can be found here.
Place the dock on the dashboard and feed the wire down into the space where the stereo was.
Plug the required connections into the communications unit.
On the back of the unit is 2 clips.
This clips over the metal frame behind the stereo.
Plug the communication unit into the back of the stereo. Replace the stereo.
The dock base twists to line up a hole that one of the screws goes through.
You have 4 settings depending on the angle and side you put it on the dash.
Ideally you should place the dock on the opposite side of the dash to the steering wheel,
decide on your placement and screw it to the dash.
The navigation unit pushes onto the dock.
When the navigation unit issues a voice command, it mutes the stereo and plays the command through the radio's speakers. The display changes as it happens to let you know what is going on.
Don't leave the navigation unit in the car, it will just get stolen.
You will probably not get a case for it, you can pick up cases on Ebay for
the Garmin C510 but the case for the original Tomtom fitted it ok.
You don't necessarily have to attach it to the dash, with a bit of creative modding you could fit it a few places. Check that the unit can receive a good satellite signal where you decide to place it.
With this and many other Garmin sat navs you can change the pointer, in this case, make it a smart.
