is now hooked up and working. Thank you for your suggestions. Here is correct wirng to connect a Uniden M525 DSC
capable VHF radio
to a GPS
, in my case a Garmin 76 which outputs NMEA 2.3.
1. Uniden Radio (+)GPS data IN wire ( white) to GARMIN/NMEA data out wire
2. Uniden Radio (+)GPS data OUT wire ( Green) to Garmin/NMEA data in wire
3. Uniden (-) Radio GPS data IN & (-) Radio GPS data OUT wires (Orange & Yellow) to GPS ground wire.
Uniden indicates that the radio "requires" an NMEA version 3.01 signal. However, NMEA version 2.3 works perfectly.
