Actual car holder/mount may not be as good as the Chinese one suggested by rainisto, but other features are interesting.

I found a bunch of other decent options...

Turns out Brodit is far cheaper if one buys from eBay retailers based overseas, instead of via that Australian reseller.
So after ruling them out, they're now back on the short-list, plus there's other interesting options in that eBay search.

$129???????????

http://www.ebay.com/itm/New-Car-Kit-...-/170957360416 this sells for australia too.

Thought I'd share a cheap DIY method for anyone that already has a garmin nuvi style mount in their car or wants to use one as a vent or dashboard mount. I've been using this for a few years now.

Vent mount:
http://www.ebay.com/itm/IG-A03-Sprin...item4cfcbc1e3a
There are a few different kinds, what’s important about this one is that there are spring-loaded clips that ensure the mount won’t just slide off after a few months of use. The N9 and this assembly seem to be light enough that they won’t break the vents on my Honda Accord, and I can still move the airflow switch.

Clip:
http://www.ebay.com/itm/BKT300-Garmi...item35a4d9eb7f
This is cut down and attaches directly to the phone case with double sided tape, I’ve tried epoxy but it was unable to withstand heat and the phone+case ended up sliding off the clip. I had a roll of Scotch Permanent Outdoor Mounting tape and it has remained secure for 2 years in 90 degree+ weather.

Phone case:
http://www.ebay.com/itm/Snap-on-Rubb...item4601027de6
The phone slips in and out of this case easily. Unfortunately, the cutouts were a little bit off on the back but they do not block the camera if you intend to use this as a dashcam. I ended up cutting this in half to make it easier to insert the phone and to avoid unnecessary stress on the right side hardware keys as a result of putting in/taking out the phone.

The finished product costs less than $10 USD (there may be cheaper sellers, I just picked ones that sold items that look the same as what I bought years ago). I don't have enough different devices that a universal holster would benefit me, and I am not really a fan of the mounts Proclip has for my car, so this ended up working out best for me. The vent mount is the most expensive part in this and it's reusable if I ever get another phone down the line.

I use the belkin window mount


works well.

Yeah I msg'd them & they explained some time ago that edeal8 (an affiliate) do ship to Australia.
But edeal8 don't have the N9 holder/mount in stock, your suggestion does!
So I've ordered the N9 mount/holder via the retailer (e.topsell) you suggested.
There is quite a long delivery/wait time, but given the price I can't complain.

Just in case it turns out to be crap, this eBay search remains on my short-list:
http://www.ebay.com/sch/Mounts-Holde...efLoc=2&_sop=3
There's some much cheaper Brodit N9 options there, + a few other interesting options.
Then the final option on the short-list is....

http://www.ebay.com.au/itm/Carcomm-P...-/270916914683

So can anyone recommend a good car charging kit & aux-in cable to use with this holder?
Ideally the new head-unit I buy supports BT audio stream, so a cable isn't needed, but I'll get it anyway.
If it makes things easier, I can provide more details about the car & head-unit.

As good as a holder/mount tailored specifically for the N9?
See the one suggested in this this thread...

Getting quite off-topic, but if anyone has some knowledge in this area please do share:
Has anyone bothered fitting their car w/a after-market antenna config. for better: DVB/DAB/Cellular/GPS reception?
I guess it'd only benefit the head-unit, as there's no way to interface such a antenna config. with the N9, no?

Forgot to mention that there ofcourse are air vent versions avail too http://www.ebay.com/itm/EN1031-Car-P...-/221039818892 just in case people dont like the suction cups.

For quite nice car stereo integration http://www.gromaudio.com/ offers pretty nice post install boxes for quite a range of car models. Offers bluetooth streaming & usb harddrives & aux & android phone clients.

I've installed one box in my Volvo and it integrates quite nicely to volume and next/previous buttons on the car wheel. So I can control my ssd drive which on glove compartment from my wheel.

Not directly releated to car holder as such. Just mentioned if someone would be interested post-install systems on their cars.

Cheers mate,

I have a thread dedicated to finding a sophisticated head-unit, but I've settled on something much simpler there.
I just can't justify the expense when it's unlikely I'll have the car for much longer, plus, it's a very old car.
If you've got a minute perhaps you can weigh-in there, up to you, I've bookmarked your suggestion for next time.

*BUMP* for my final Questions in post #26, TIA...

Actually, looking at just one of the main retailers who sell this sort of stuff, there's 2x suction_cup versions & 2x aircon_vent versions.
They're all so cheap, I'm srsly tempted to buy all 4x instead of just 1x of each, what do you reckon!?

Aux-in cable I imagine is pretty bog standard, my local "bricks & mortar" should have something suitable.
But if anyone can point some stuff out that I may not be aware of, please do.

Any insights here, please? Thank-you!
