Power issue with the 2599 - is this normal?

alan_sh

I ook my Nuvi 2599 (The Halfords version of the 2598 I think) out in my wifes car.

I didn't have thr power lead, but she had one which she uses with her TomTom 930. I plugged it in and the Garmin immediately went into "Garmin Express" mode.

I tried everything i could think of to get it to do sat-nav when powered - no joy.

So, is this normal - it needs its own power lead and no other will do?

cheers

Alan

It can do that if you use a USB lead and not the ciggy socket lead as it sometimes thinks it's connected to a PC.

From memory, TT's have a third connected wire in the cable and maybe that is confusing it ?

Some time ago I bought a usb connector for the car power point and it made my TT 530 think it was connected to the computer. Generally my usb connectors have never had such a problem, perhaps a problem with some cheap chinese sourced plugs?

No, it doesn't have a cradle - the power lead plugs directly into the back of the Nuvi.

Thanks for the update. I may see if I can "hack" a lead which I can keep in the wifes car.

Hi,

I'm new to Garmin SatNav devices but familiar with TomTom to some extent.

I believe the TT cable is a pure USB cable with DATA leads connected so it can communicate with a PC and also act as a power source.

If you click on my personal BOX.net account link below ( no adverts or crap like that, I promise ) it will show you the lead configuration with all cable lead feeds.

I can only assume that certain Garmins have the DATA leads connections disconnected on the cable so it acts like a PURE power supply for the devices.

The ground lead on the cable is the 'Negative' supply and the 'RED' lead is Positive supply. The DATA leads are normally the two inner connections

I haven't purchased my first Garmin SatNav yet ( I've posted on this board for advice on purchasing the best one for my needs ) therefore I cannot confirm absolutely that my analogy above is correct. A simple multimeter or continuity tester on each end of the USB leads will give you the best answer.

I hope this is of assistance

Regards to all,

John in the UK

You need to use a Garmin specific lead. It's possible that some others might work but it'll be on a trial and error basis. The alternative is just to purchase a standard Garmin power cord to keep in your wife's car.
