Settings for wireless data service using Sprint Touch Pro and TomTom Go 720

[dubhead]

Folks,
I have torn my hair out looking for the appropriate settings to use when pairing via Bluetooth a Sprint Touch Pro and a TomTom GO 720 GPS unit. Yes, yes I know the Touch Pro has built in GPS and all that but I use this TomTom in my wife's vehicle and keep my Touch Pro in my pocket . It does successfully connect via Bluetooth and can share my contacts and make and receive calls all through the TomTom GO 720...BUT...it won't connect properly for the wireless data services to work. Basically the TomTom unit is asking for some simple information to connect to the phone and initiate the #777 data call.

The real killer to all of this is that I have had this working almost a year and half ago with my PPC-6700 and don't remember exactly the settings I used. All the advice I have read (and tried!) in almost every nook on the net has indicated small variants to the following sequence in setup on the TomTom:

|TomTom asks: My response|
Select your country: United States
Select your provider: Other (Sprint/Nextel not listed in providers)
Do you want to set up your connection manually?: Yes
Access Point Name: (leave blank usually but have tried Sprint PCS, Power Vision, Sprint PCS Vision)
Username: (leave blank usually but have tried mysprintusername@sprintpcs.com and mysprintusername) where mysprintusername is my actual username
Password: (leave blank not sure where I would get this anyways)
Do you want to obtain your IP address automatically (DHCP) or do you want to set up your IP address manually: Automatic
Do you want to obtain your DNS server address automatically or do you want to set up your DNS server address manually?: Automatic
Dial: #777
Login script: (leave blank but I do seem to recall using a modem like AT script before to initiate the #777, maybe that is where I am striking out as everyone says leave blank)

TomTom GO 720 then tries to use these settings to connect to the data service via Bluetooth and then asks if I want to repeat the process.

I have looked in XDA dev forums and there is a similar thread on this topic with no answers for me that work. I think if we can get this solved here, we will be doing a lot of folks besides me a lot of good. I think a number of people were told that you just couldn't use the Sprint network through the TomTom GPS device which is a load of BS.

Thanks for any thoughtful input into this issue!!!

Cheers!
