If the GPS has been turned off for a significant time, and especially if the unit has been moved a significant distance, the first fix can take a long time.
If you leave the AIO out for that long period of time, and it finds a fix, future fixes should be much quicker.??
An example of this happened to me on a vacation.? I hadn't used a particular GPS module in about 6 months.? I grabbed it and took it on vacation to use on a hike in New Mexico (from Michigan).? Happily, I powered it up the nighf before, in the hotel.? I can't give a time frame, but it took a long time to get a fix.? Powered it off, and the next morning on power up, it had a fix in "seconds".
I'd give that a try, first, before sending it in.? GPS modules 'usually'?don't go?bad.

Marc,
The green flashing LED on your AIO indicates that the device is waiting for a valid position to be calculated by the GPS. If you have left your AIO off for a very long time, I suggest letting it run on its "back" ( i.e., GPS facing the sky) and let it run for a couple of hours. There is a small chance your GPS will come back to life given enough time to find itself in the universe.
If the GPS is kaput, it will need a transplant. Older MT-AIO's use a different GPS connector than the new GPS receivers, so the transplant requires removing the GPS from the MT-AIO board where it is mounted with double-sided foam tape. The new GPS wiring harness must be spliced into the old harness, or in the case of very old boards, soldered to the PCB. Three wires have to be spliced this way, and they are fragile. You can purchase a new GPS receiver from Byonics for about $65.00, it is called the GPS5OEM module. ( Note: you can also install the high-altitude GPS which costs a bit more)?
If you would like to send your AIO to me for repair, I will do so for the cost of the part and $10.00 return shipping. ( I am the manufacturer) You can send me an email at allen@... to discuss this.?

Robert:
TY for the reply.
Here are my observations:
1) I do not understand how the GPS indicates there is a fix.? I assume its related to the green LED.
Upon powerup, the TT3 TX one time (one red flash of the LED) then it blinks (continuously) Green at roughly 1hz rate and never appears to TX again (noted by a nearby HT with no antenna).
2) there is no radio involved in this setup, its an all-in-one unit.
Me thinks that the GPS portion is amuck.
Many thanks
