5.14 Setting Up Dial String Codes for
Automated Phone Services
You can program the NavTalk to dial DTMF
Tones for a wide variety of automated phone
system services. You can program calling card
PIN’s, link phone numbers from the PhoneBook
page, pause in a dial string, stop dialing until
you press send again after listening to prompts
at the call destination, and to transmit your GPS
position via DTMF tones.
NOTE: When you add a Dial String Code to a number
string you must use the UP or DOWN Rocker Pad Arrows
to enter the code. These keys display only the code letters
and numerals used to create a dial string with DTMF
tones.

string for your DTMF application use the follow-
ing codes to create appropriate pauses, stops and
links in the dial string. Shown below is a chart
