The two front screws are all that is required if the rear mounting stud lines up and is used.

Most times it doesn't and isn't....

Here's the OEM Nav HU...

This picture clearly shows the hole the stud fits in...

Thanks, Wpoll. I wonder if the "stud" can be transferred to the new HU? I'll pull the HU back out when I get a chance and see.

AM.

The stud is threaded (M4 or M5 maybe), so re-use depends on a threaded hole in the correct location in the new HU - some have this, some don't.

Nope...

looks like the one you ordered is out of stock for the px4 and px6 and only the 2 4G LTE's arfe available with an extra cost. I am not interested in 4G. Any suggestions?

Avin Avant 4. Been very happy with mine.

I've just installed an Xtron IX1253BHL and it was a VERY VERY tight fit to get in the dash. I had to bang away some of the plastics on the sides of the HU hole to make enough room to get it in and even then it's wedged so tight I didn't even need screws.

Overall it's ok but there are some pretty bad issues which are really pissing me off.

1. the volume ramping is just ridiculous! Going from 3 - 4 on the volume gives over double the volume. It's just so stupid. Where is the smooth volume transition? Set at 3 it's too soft, 4 too loud.

2. The native Tidal app from the play store is totally unusable. After you select an album and play there is absolutely no way to get back! All navigation functions are not shown. All I can do is skip forward or back a track on the album. PERMANANTLY!

3. Spotify app leaves all the junk at the top of the screen when playing a podcast with video. It doesn't fade away or anything so you are left with crap over your video.

4. There is some engine whine which I have no idea how that's even possible since I have factory DSP and ran the 6m cable straight to the unit. Bizzare.

5. I have no ability to change screen sizes when watching Youtube or any other videos. I'm stuck with what it defaults to. This sux.

6. When using the units DSP module, when fading to the rear the sound simply goes quieter then disappears. all speakers work when left in the centre.

So yea, I'm somewhat disappointed after having high expectations..........
