Finally got round to doing this as the weathers been rubbish.
got this unit Eonon 2167
Pretty happy with the result - ended up not using the cage as it was quite a tight fit anyway, used the padding though to keep it steady.
the facia kit
was a really good fit, really neat although it needed a tiny bit of persuading to get it all together.
the dynamic sounds connection block thing
was the bizzo, everything labelled and pretty straightforward.
I did as much of the loom beforehand. (everything i needed was included)
for some reason i hooked up the reverse wire even though i didn't get the camera so now it shows a blank screen when i reverse..
aucht well not to worry, maybe i'll get a camera and sort it.
this only really left the illumination wire to piggyback on to the ashtray bulb in the car, and the rx tx bus wires which i didn't use.
I have no idea where the audio jack from the dynamic sounds connection block goes - i left it dangling - it didn't seem to make any odds anyway as the reverse sensor beeps etc still all work regardless.
The volume is pretty loud even at low settings - I knew this would be the case and it's no great issue, (amplified at radio and back amp)
The scariest bit was removing the air vents at the top - they basically fell to bits and despite my best effort at reconstruction i don't think they would cope with another mauling. If i ever have to remove them again i'll probably need araldite to get them back together.
I left all the cds in the old system like a numpty..
best bits are:
Hooked up usb with stacks of tunes
the new Google Driving app is brilliant and you can set up all your favourites etc from your PC
mobile tethering works well
bluetooth is good and call quality is par with the factory parrot I removed (its demise was the main reason for this project tbh)
the very very best bit was finding out how easy the ashtray, glovebox, dashboard endcaps, aircon controls and lower side trim panels were to remove and refit.
Cursing the vents then finding out the rest was peachy made my day.
I'd recommend giving it a go it wasn't nearly as complex as i imagined,
