What phone to buy for GPS?

I shall be changing my mobile phone soon. I'm currently on Vodafone and would prefer to stay with them. I'm considering the Nokia 6680 and a bluetooth GPS receiver. I'm currently using TTN5 on a PPC so would expect to use TomTom Mobile on the phone. I'd appreciate suggestions for what the receiver should be. In addition, this will be often used on a motorbike, hence I would be using a bluetooth headset. Can this or any other phone have two bluetooth connections, one to the headset and one to the GPS receiver?

Regards, John

Don't know if it possible with a smart mobile like the Nokia.

It is certainly possible with a PPC 2003 based phone system - I have my Ipaq 6340 talking to both car kit and sat nev receiver at the same time. However I am told it is not possible with Palm based PDA and Phone systems - they can only have one BT connection open at a time.

I am not sure how correct this is but I remember reading that one of the limitations to bluetooth was that it only works with one device at a time. Hence why WiFi has many advantages.

The conclusion is that the techies were working on a new bluetooth technology to enable several pieces of kit to talk to one another at the same time, but I would guess this is not available at the moment.

You may need to consider a combination of connections, bluetooth, wifi, cable to match multiple connectivity.

Thanks for the input. I guess that's what I suspected, that either the bluetooth talks to the headset or the GPS but not both. It looks like I'll have to use a wired headset then. I do have a 2.5 mm jack to bluetooth adapter so a phone that had a conventional headphone socket could work but the Nokias have this "pop-port" now

Any suggestions for alternative series 60/80 phones and bt GPS units?

Regards, John

Hi jrisch, have just read this thread, and I am in the process of setting up a system using bluetooth for use on a motorbike, and you can have more than two devices linked together using bluetooth. Take a look at this site www.bluetooth.com/Bluetooth/Learn/Works/

It states "During typical operation, a physical radio channel is shared by a group of devices that are synchronized to a common clock and frequency hopping pattern. One device provides the synchronization reference and is known as the master. All other devices are known as slaves. A group of devices synchronized in this fashion form a piconet"

So there you go

Looks like I'm a bit out of date with bluetooth then.

So if I understand right, with the old bluetooth you had a pair of devices but with the newer bluetooth technology (BT1.2?) you can have several devices connected to a 'master' all active at the same time. Fro what I see that is up to 7 devices in total ?

OK that looks far more useful then, however, I'm sure all the bluetooth stuff i have (old motorola phone, headset, PC USB adapter) are all old school.

Does anyone know if you can use a newer device as the master and older ones as a slave, I would guess not but could be interesting.
