Hi,
could anyone tell me if it is possible for the ps2 style connector on the 6010 to have a converter to rj11 (lan like fitting) also if it is possible, does plugging the rj 11 end into a tomtom mount charge the gps or just link it to the pda.?
The problem i currently have is that the tomtom mount has one main power source, and the pda slides onto the fitting to charge and to link etc.
but my gps needs to be plugged to the bottom of the pda, and a dual charger charges both the pda and the gps.
Im trying to make it so my 6010 will simply plug into my tomtom holder, and i connect a single power adapter into the mount which powers the pda (although im not sure if it would power the gps through the rj 11 connection)
at the moment i have to unplug my gps from the pda everytime i take it out of the car.
You have probably solved your problem by now, but here is what I did.
Like you, I wanted to use the TomTom pod and came up against the misfitting plug problem. I asked Rikaline for help and all I got was 'you cannot get an adapter'. So I decided to make my own.
As you say, the Rikaline comes with a mini-DIN or PS/2 type plug, and the TomTom requires a telephone-type plug (in the UK it is the plug that goes into the phone itself not the one that goes into the wall). Probably the easiest way to get these plugs is to cut the PS/2 one of an old mouse and to cut the phone one off an old phone, though in fact I was able to acquire a PS/2 one from my local electronics knick-knack shop.
Now you need to do some simple wiring investigation - a multimeter is essential. Four wires run between the IPAQ/TomTom plug or pod (and hence the IPAQ when it is plugged in) and the GPS receiver. Two of these supply the power, and two transmit the data. With the original Rikaline set-up, the voltage is stabilised in the car adapter plug and runs in both leads - one from the car adapter plug to the IPAQ and the other from the car adapter to the Rikaline. In the TomTom set-up, the car adapter is just a passive plug and the voltage reduction is done in the TomTom pod - both for the IPAQ and for the GPS.
Using the original cable which came with Rikaline (and with the IPAQ well out of the way) I identified which pins carry the supply (it is 5.1 V), paying particular attention to polarity. I then powered up the TomTom pod and identified the two wires there which carried the supply (again without the IPAQ anywhere around), and again with attention to polarity. I then soldered the wires in appropriately. This left me with a second pair - the data wires - which I just soldered together, polarity being irrelevant here. You may need to open the PS/2 plug on the original Rikaline set-up to work out which four of the six possible pins are actually used.
Slightly to my surprise, when I had worked all this out I had got it right and my IPAQ now works happily from its TomTom pod with the Rikaline GPS receiver.
Good luck! Remember it is the polarity of the power supply and getting it onto the correct pins which is crucial - the rest will follow, but if you get that bit wrong then damage to the electronics is highly likely.
