Since this is a mammoth post, tech details and story, a reward will be offered for help that directly resolves my problem. (nature of reward is undecided as yet)

Hey

I'm back from my hiatus, I'm sure many people were worried and perhaps a search party or two were organised. You can all relax and finally get a good nights sleep:shifty:

I have a Nokia N70. I have purchased the Nokia CK-7W car kit (advanced wireless car kit). I'm having the kit fitted along with alot of other accessories in the next week or two at the latest. I really want to get this done all at once, rather than have to go back a second time. I've searched for 1 to 2 weeks now on the net (world-wide) and locally in NZ, without any real luck/help. Here's my dilemma:

The main problem is that Nokia in their wisdom decided to release a top level, business orientated mobile (N70) without full support for certain features. The Nokia 6680 (the previous model on which the design of the N70 was based) has a specific cradle (phone holder) which works with the CK-7W car kit. That is the CR-27 cradle. The N70 does connect/fit with this cradle, but you have to attach a sticky backing to the cradle, and align it carefully when inserting the phone. Even with this, it is prone to disconnecting from the data port in random situations (bad roads, etc)

That CK-7W kit can be connected in two ways. Firstly the Bluetooth connection, which functions perfectly with all the features working as intended. This method I have no problem with and most likely will be the method I end up using. With this option, you can keep your phone in the glovebox, briefcase, boot, etc... You can also use phone functions, but you need to pick up the phone (I only have 1 arm now)

Second method, is the cradle/wired method. The only difference between the two is that the phone fits into the cradle in the second option, where it connects on to the data port at the bottom of the cradle. That port on the cradle connects to the CA-27 data cable of the CK-7W car kit. The benefit of connecting this way, is that your phone is visible when driving (easily see who's calling, make calls, etc...), the cable also supplies power (charging your phone), and the BIG benefit, connecting an external aerial to the cradle to boost your signal strength in remote areas.

Since Nokia don't make a cradle, I finally found a nice one online in the UK which I have just ordered (the SECOND item, bottom of the page at http://shop.dashmount.co.uk/installation/nokia_n70holders.asp, the 39.95 pound item).

That will give me full functionality (car kit features and charging), EXCEPT, that cradle doesn't come with a connection for an external aerial. The extra aerial works by connecting a suitable aerial with an antenna coupler. Then you fit the antenna coupler on to the cradle. When you put your mobile into the cradle the part of your phone that houses the aerial circuitry touches the antenna coupler. The signal boost is received through electro conductive magnetism, as I understand it. With the design of the cradle I'm getting (in the link above), it should be really easy to neatly attach the antenna coupler, which would act as a back rest / plate for my N70. The aerial sits in the back of the top of the phone.

With the carkit, I also bought an external antenna just in case, which is the correct part for the CR-27 cradle, for the previous model Nokia 6680. That aerials details are: Premium on-glass GSM Antenna BMIS-ANT-STD
with the following on the actual plastic packaging: Part No GC923-4MFL
I researched then ordered a coupler and antenna from the best company I could find online (www.expansys.com.au), but they replied saying that they had no experience with this setup, and weren't sure if it would work. They suggested another combination of: Nokia AXF-15S Antenna Coupler (http://www.expansys.com.au/product.asp?code=AXF-15S) and Skymasts DBS1 Cellular Windscreen Antenna (http://www.expansys.com.au/product.asp?code=DBS1). I had those on order, but they replied again saying they don't have any knowledge over compatibility of this setup, and thus cancelled my order (which is fair enough, they're trying to prevent me wasting my money and trying to return the order I guess). I even said that I was willing to take the risk (they aren't that expensive, about $78 for antenna and coupler), but by then they were getting pretty annoyed with me (I assume it's because the research is taking up their time).

Does anyone have any idea how I could resolve my frustrating problem of attaching an external aerial (I presume it's always a combination of aerial and coupler) to the N70 cradle I ordered? Otherwise any comments, advice, experiences or suggestions would be greatly appreciated.

Thank you.

Hi Stonechucker, good to see you back on KB again....


As to your wee problem, sorry mate I have no idea...
But I reckon there will be someone on here with some great ideas.

Do you really need the external arial? the only way it will boost your signal is if there is an inline signal booster attached to the cradle unit, which if my memory serves me right, nokia dont have one.

Your mobile should have the necessary power to give you the signal range, the only time your signal gets weak is due to speed, the quicker you go the worse it gets.....

I have always used this set-up in the UK and never had a problem at all, I have tried the external area but never noticed the difference and I was using a Bluetooth kit and not a direct cradle link, which will always give you better clarity.

Hope this helps, if not I wont be offended:ride:

Do you mean the Bluetooth connection gives the better clarity? That would be comforting to hear. The main reason I wanted the signal boost is for when I drive around remote places, which I plan to as much of as I can.

I know Nokia don't make a N70 specific cradle, but as I understood it, they do make a specific cradle (CR-27) for the Nokia 6680, which I assume has a connection for a coupler/external aerial, for use with the CK-7W car kit.

If it cannot be done, then I guess I'll have to be happy using that cradle I've ordered for the 3 things it supports/achieves, that being car-kit functionality, charging and visibility. From all my research, that cradle I ordered is the only one you can get that is specifically designed for the Nokia N70. The more I think about it, the more I realise that I probably won't need the signal boost of an external aerial.

Still, it would be nice if the option was available to me.<_<

Can't someone in one of the companies specialising in fitting car kits help you out? It seems like something they'd be intimately familiar with.

Hi stonechucker, welcome back. you could try a bit of plastic-weld to connect the two items, after ensuring the coupler is compatible. That way the coupler only has to be compatible with the h\set. Alternatively whats wrong with just a bluetooth headset with voice activation which is usually a feature on the Nokia's? Have I missed something? hope it of some help.

Already called and asked / explained my problem. They are brilliant at installing car-kits, connecting cradles and external aerials&couplers, but only with compatible components. They won't install something that they think might not work, or something they haven't yet received information / tech specs on...

When I get everything fitted, I'll of course ask again, but I've heard all the replies already

That was way to much for me to understand so i'll give you the guys number we use at work to install our car kits....

The guys name is Scott and he works for TGT Installations 0274855799.

He should be able to help you out just say Torsten from Wairau Road gave you his number

Whatever happened to GoodOldKiwiIngenuityAndPioneeringSpirit ? :spudwhat:
There have been some good examples of that exhibited here in the replies, and I'm sure there's an auto-electrician/car kit installer out there somewhere who's got a few clues or is willing to experiment. At the least, you'd think one of these companies would be willing to at least temporarily 'fit' something in your car and see if it works.

That's exactly what I was trying to do, that is, get a compatible coupler & aerial, and then modify/attach a back plate on that cradle I ordered where the coupler would sit, right where it should be in terms of orientation to the phone (touching the phone where the aerial circuit is housed)

The problem is that I can't find (company won't sell) a combination of aerial/coupler for the N70, as none have been tested or released yet. There are lots of couplers & aerials on the web/in shops, but there is little or no evidence that they work with the N70

That's what makes shops hesitant / refuse to sell them for this application.

Thanks for the contact. I am already dealing with one auto-electrician who is installing a host of other items, so I'll ask him first. I'm sure if there is some way to "no. 8 wire" it together, most qualified people would be willing to have a go. Another complicating factor is that I'm perfectionistic & obsessive compulsive. I could not live with anything other than an amazing, ergonomic and stylish modification/alteration, but preferrably a solution using manufactured parts to connect the kit.

k ive had time to read now.


Any of those aerails you mentioned will be compatible so long as its GSM (any GSM aerial will work)
In saying that though getting an external aerial will not help your cause in terms of recepiton quality to a noticable degree, as the phones you are talking about are digital and the digital signal cannot be boosted like the older analog ones could be. The most you might get out of it is about 50m and in my opinion not really worth the effort, your better off saving your money

Not sure about the phone your are talking about though since its not in our range so im unfamiliar with it in terms of cradles and couplers

hope this helps
