Carpuride w701 VW Polo 9n3 dash tray riser mount

To fit the mount you will require:

*M3 50mm bolts x 4 preferably countersunk (45mm should work, the 40mm I had on hand were too short)
*M3 nylock nuts x 4
*M3 washers x 4 (optional - should help prevent the nuts damaging bolt holes in plastic over time)
*4mm drill bit
*sharpie
*16mm (iirc) drill bit/spade bit or similar (optional - for cable hole if you wish to run then behind head unit etc)
*Nylon spudger/pry or similar
*(optional) Replacement 9n3 dash tray from Aliexpress if you do not wish to damage your original. They are AU$15 delivered for me, well worth not ruining your original OEM dash tray as they can be expensive second hand if you wish to reverse the mod at a later date, who knows how this unit will last)
*Filament better than PLA if you want it to last in the sun, I used PC/Polycarbonate.


Instructions:


1)Print the mount in something better than PLA, polycarbonate seemed to be most recommended. I've printed this one on a Bambu A1 using Generic PC settings, 0.4mm nozzle and the Extra Draft 0.28 layer height. Despite warnings online of not printing PC without an enclosed printer, it printed acceptably fine (possibly helps it is a simple shaped print). Having no support for the cable hole seemed to work fine as well.

2)Pry up the dash tray with a nylon spudger from the top left or right (it's easy, use youtube guide if unsure), 

3)Print template in PLA or whatever is easiest, use a sharpie to mark holes in dash tray using the tabs on the template to roughly align them. The template should be facing in the orientation shown in the yellow template photo as if you were looking at the dash tray from the front seat. 

3)Drill 4 mounting holes and the optional cable hole if required.

4) (optional) Remove your head unit, feed any required aux/power cable through the passenger footwell, back of your head unit etc, and then the ends of those cables through the dash tray hole. I used a flashlight to find a route to feed the small end of the cigarette cable adapter, using a cable puller to make it easier to feed the cable upwards. The Aux cable I fed plugged straight into the back of the old aftermarket head unit, I don't believe the OEM unit ever had an Aux in.

5)Attach the mount with the (optional) cables routed through the models cutout using the m3 bolts/nuts and torque them down decently, being careful not to pinch the cables. Washers under the nuts are recommended to prevent the holes being damaged over time with vibration etc.

6)Install the unit on the mount, plug in cables, place tray into place, put head unit back in. You're done!




Note: My partner has only had the carpuride unit in her car a short time, while the mount works great, I'm not sure I can 100% recommend the actual unit itself. The Android Auto is fast and great, but we've noticed when someone calls they hear a bit of echo/feedback received of their own voice, which is caused by the onboard mic picking up the car speakers. We've found lowering the car stereo volume during calls helps a little so far. The old aftermarket head unit had a mic routed/installed behind the rear vision mirror, but it uses a 2.5mm jack, so we're waiting for a 3.5mm adapter to be able to test whether this external mic will help.

Probably this is just a symptom of the Polo being such a small car and the close proximity of the onboard Mic to the door speakers.
