Touchstone on/off problem solved in the car.

cubefx · 02:33 PM

Finally it worked!

I originally bought car Palm 1000mA charger for my touchstone setup. Unfortunately my TS started to have ON/OFF problem in all of my cars every time I used my blinkers, pressed the brake pedal or turn on my headlights.

I tried different TS and another Palm car charger, but nothing helped.

Couple weeks ago decided to give it another try. Ordered 1200mA USB car charger for PSP (they advertise 2000mA, but it is not true). $12 shipped from HK. Got it in about a week.

To make it work with a Touchstone you will need to take it apart.

And solder contacts 2 and 3 together.

Works perfectly! I am using it for the past two weeks in 4 different cars without any problems!

What does soldering the contacts accomplish?

Shorts out the data connection to enable fast charging method.

Cool. I'll give it a try. Occasionally my charger acts up and I haven't yet figured out why. It was only $7.40 shipped so it's worth a chance.

Touchstone will not recognize the charger if those two contacts are shortened. Shortening the contacts sends the signal to the TS that the charger is compatible and TS will allow charging.

Here is little bit more info.

Instead shortening #2 and #3 pin in the USB cable I shortened the contacts in the charger. It is much easier this way.

In case anyone is confused, cubefx means "shorted" not "shortened".

Did you receive the charger and perform the mod? Can you tell me if you had the same results? I'm about to order this charger since I'm having the same problem with my '05 Highlander.

grandebob · 08/26/2009, 04:15 PM

I was looking to order one, or something similar for myself, however that page doesn't seem to use SSL. Scarey.

slick5150 · 09/05/2009, 09:00 PM

FYI - I ordered one from them and received it, did the mod, and it does indeed work fine.

I then realized I really don't have much use for it, so if someone wants it and wants to paypal me a few bucks to cover the cost for me to ship it to you, I'll gladly send it to you. Send me PM. You'll need the usual USB cable to plug into it.

sent you a PM

I ordered and received one of these, and did the solder mod. It does work quite solidly and so far I have noticed no on/off glitches.

I have the Moto charger which works great EXCEPT when the car gets hot in the sun, and I have the Palm charger which works pretty well but does the on/off dance when the car's 12V supply fluctuates.

jbg7474 · 09/10/2009, 10:02 AM

I tried the Palm charger recently with the Touchstone and found that it didn't quite keep up with the Pre's draw when running Sprint Navigation and playing music (through the music app, not Pandora) simultaneously. I have some theories as to why that might be, but it sounds like something greater than 1000mA might help.

Does 1200mA keep up (or charge a bit, ideally) with max draw on the Pre when used with the Touchstone?

pchrist · 09/11/2009, 10:49 AM

Slick if your still interested let me know and we can get something done. Just waiting for you to get back to me.

pchrist · 09/14/2009, 09:31 AM

ok just bought one we will see how it works! hopefully it doesn't take to long to get to me. then i can take the palm charger back.

Rkguy · 09/25/2009, 06:24 PM

just curious to get a follow up report on this, possibly with car model and driving (temperature) conditions.

wodin · 04:11 PM

Why don't one of you young entrepreneurs out there find a manufacturer to make mini to micro USB adapter that will fit a TS and has the data lines shorted on the micro side and open on the mini side? The mico plug would have to be small enough to physically fit in a TS without shaving! You could have them made in quantity for, say 27 cents, and sell them on PreCentral as "TS charging adapters" for ... oh ... $8.99 plus shipping.

That way you could use ANY mini USB charger (with sufficient power). Mini USB cables are ubiquitous, I have dozens of them myself.

I'd buy three!

Hint! Start by googling "custom cable manufacturer"

Or, I could just modify one of these

Just put the phone on vibrate and you won't here the charging sound. Music still plays
