Lexus LS430 2005 Bluetooth Treo 650

by tellit / February 14, 2005 2:14 AM PST

I have been able to pair my Lexus and my Treo650 but I had to disable "call waiting", because everytime another call would come in it would hang-up / disconnect both calls. I am unable to use the phone book, signal strength and etc.

I really need to be able to use call waiting ! Can anyone assist me ?

Treo 650 call waiting
by potzel1 / March 12, 2005 5:45 AM PST


I am experiencing the exact same issue, I've called Sprint's technical support and he told me that this issue was never reported to them, I think we have to make sure that as many people report it maybe they will do something about it, Its terribly annoying.

You might try contacting the manufacturer of the phone, I don't know that your cell provider can answer that question/problem.

My Call Waiting works great with my Bluetooth headsets and all other times. It is only when I use the bluetooth in my 2005 Lexus LS430.

treo 650 ls430
by sschiffman / May 24, 2005 11:33 AM PDT

i have a cingular treo 650. i have loaded all the updates. to get the phone to pair merely go through the process and when the phone acknowledges pairing (even though the nav screen is still waiting) place an outgoing call from the phone that will pair the phone.

the problem i have is you get one call then the connection drops. ocassionally it reconnects. you only get a connection if you have installed the car kit update.

basically it is worthless with the ls430. works fine with our accura. a cingular dealer says lexus has a fix. i will be calling them to find out.

Treo650 and Lexus LS430 Bluetooth

In reply to: call

I don't want to bother you with a phone call, but can you help me? I have a Palm Treo650 using Cingular and an LS430 with Bluetooth compatability. I can transfer phone numbers to the car, but can't make outgoing calls by using the LS phonebook. The screen indicates a call is in progress, but the phone is not placing the call.

pair any treo650 (all carriers) to any lexus model
by timmyhlexus / December 6, 2005 5:45 AM PST

There is a fix that i have discovered to pair the treo650 to any lexus model with bluetooth. You need to go into the info screen, then the telephone screen, then go all the way to the bottom of the menu into the settings screen. From this point you need to extend the passkey to six digits instead of four digits. the only carrier that i have found to support the phone book transfer is sprint. Cingular will not support the phone book transfer into the lexus. The way to load your entire phone book is to go to send catagory from the drop down menu in contacts screen. I hope this helps all that are having trouble.


If you have any more questions feel free to eamil me
