Will this unit connect to an external GPS antenna? I would be using it on a dashboard inside the boat cabin.

not sure the antenna connections are compatible. generally traditional boat use VHF's are 25 watts and these hand helds are only 5 watts. i would not buy this radio again

We use a high gain antenna and signal amplifier in a marine application with this unit. Channel tuning while the boat is moving is not very good. I spoke with a local car audio company and they indicated that this is a common problem with all digital TV tuners. That is, they don't work very well when in motion.

As long as your Lowrance has NEMA connections,and you properly wire it,as mine took a bit to get right.Mine is interfaced with a Garmin,and as soon as it finds satalites,your ICOM will display "GPS" and will also display gps cordinates,time,etc.It took some reading of the manual,but I will never go back,I love the fact that I have one distress button to hold in case of emergency and help some shape or form will come.Oh ya dont forget to register your boats name..etc..so you can get a MMSI # (its free)and program that # into your radio,so when/if you need to use the DISTRESS button the Coast Guard know exactly who's calling. Good Luck

This is a car unit only. You have to be within a couple of feet of the inside antenna for it to do any good. You'll want to look at a home/office unit instead for what you're trying to do.

My understanding is the GPS antenna is a separate part that does attach to the GT680W so there should be no problem. I didn't order the GPS unit myself though. Don't need special software. I have reviewed video and my computer played with no problem. Should you have a problem then use Google and/or go to the E-Prance website.

No, as a proximity antenna, but would probably work if you have an external AM plug on your unit

It will work but I will say this though you will not be able to hook up the gps due to the external GPS system is discontinued

If it's like a Jon boat yes but if it's an enclosed hull, the gain end of the antenna (non plug end) has to be exposed outside the hull somehow. That end of the antenna has to be able to have best possible reception and aluminum will distort rf signals.

I can't answer directly, as the unit is not at hand--it's on a boat in Florida and I'm in CA at present. All I can say is that it fits a Garmin 740S GPSMAP chart plotter, so whatever the standard connector is for the Garmin would be it.

I have not tried connecting it to an external antenna. Mine is connected to a Cradlepoint wireless router.

It may ... I use it in an rv and have to put it near a window for good reception. There is no external antenna port, you would have to use a clip type.

it should work fine once you google how far the nearest broadcast station is located from where your RV is Parked. Not sure it will bet good connection while Driving

Antenna is built-in, there is no external port. Save your $$$$. There are several hundred different better GPS is in this unit. This is old technology. Get a garmin.

No. The device has an internal antenna. The external antenna gives better reception if the device is mounted below deck or under overhead structures.
