How long should the GPS speedo antenna battery last ? Our's only lasted 2 years 3 months in the boat . Does that sound right?

I got 3 years out of mine. Alot of people have had issues with them.

I got the new style Head / antenna combo that does not have a battery.

Yeah, about 3 years for us also.....

Just over two years and mine quit.

I got 3 1/2 years out of mine....bad design if you ask me.

Most car GPS units power off the head unit, not sure why these don't.

Yea bad design , I talked to Mike Livorsi and some guy named Todd, To fix it with a refurbished antenna like the one I have now is $159.00 if I send the old one back . Then in another 2 years they will need another $159.00 to keep it working , or for $315.00 they will send me the new type antenna that has no battery and if I send in my old antenna they will give me a $30.00 discount.

what!?

YUP !!!!! I bet if Mike bought a TV for $450.00 and it stopped working after 2 years he would be pissed but for $315.00 they can fix it he would be mad as hell.
