Which Antenna to fit Motorola A1000?

Got a Motorola A1k and it's not quite the best at gaining fix's. So does anyone know what Antenna fit into the back under the rubber pad?
I have seen the PC-Mobile battery powered re-radiating antenna but unsure of the connections for the A1k and yet to find a site selling the kits in the UK.

Any advice/help will be very helpful.

Are you sure it has built in GPS?

Many phones are siad to have built in GPS but they are really AGPS which is not the same GPS as we all talk here.

It's got AGPS, but when using nhGPS software it doesn't talk to the network. But even so there's two small sockets on the back each with a picture. One is for Bluetooth and the other for AGPS. I was wondering if I put a antenna there would I get a better/quicker fix.

AGPS is usually network/service based which means you have to pay the network to get any such service.

I do not know how this is implemented in USA though. I guess that is where you are.
As far as I know, a few Motorola phones have such so called built in GPS and they are useable only in USA.

I'm in the UK. The AGPS only requires the network when you enter building or other area's where the GPS signal is very weak.
Other than that the phone can access the chipset of the GPS and work like a normal GPS reciever. It sometimes takes me about 5 minutes to get a fix. This is why I'm asking if there is an antenna to fit.

If these phones have real GPS as we know here, we would have seen a lot more talks about it (and many previous models) here or other GPS forums.

I do not have one so cannot stick my neck out for it.
(I have a Motorola MPx200 which is also supposed to have AGPS but it has no use except the presence of the GPS icon)

I still think they are network based features which mean you have to pay to use the features (if at all available). They cannot be used like a NORMAL GPS.

Therefore I think an external antenna is irrelevant (useless).

I took a look at nhgps.
It does indicate that A1000 (and previous Motorola 3G phones) have a working GPS hardware. with limitation.
nhgps software seems a bit limited.

May be TomTom Mobile can be used? If so then we may hear more about it.

Without any useful software it is not of much use so that may be why not many people sue it.

If it does process GPS signal on its own then a re-radiating antena should help.

I believe Tom Tom is out for the Symbian UIQ but only for the Sony Ericsson phones. This option does require a bluetooth GPS reciever.

I'm hoping Route 66 comes out as I had this for my Nokia 6600 and it was brilliant.

nhGPS is great for me cause I can attach my phone to my nitro RC truck and the record the speed and where it's been and then test the engine and mod's to see if I can get it any faster.

Anyway back to the original question......
Which type of 're-radiating antena' would be best to use, as I don't know what type the connector is on the back of the phone. It's about 3mm across with a single hole in the middle. Copper outer with a black plastic inner core, probably got a connector in the center but the hole's too small to see.
Also does any site's in the UK sell the 're-radiating antena'?

Sony Ericsson use the same UIQ7.0, do they not?

I do not know the A1000. (antenna type I mean)
Does it say on the manual?

Knowing it is a phone, I suspect the external antenna port is for the phone, not the GPS.

Any re-radiaing antenna should work with any STANDARD GPS.

Sony Ericsson is the same UIQ v7 but '3'-UK have restricted applications running from from external memory cards.

The manual does not state the connections. I've seen diagrams for the pin outs on the bottom and the regular antenna for car kits is on the bottom. But these two connectors on the top back have the bluetooth and AGPS symbol.

So where in the UK can I get a re-radiating antenna?
