Need Help Diagnosing GPS Problem
Recently our main GPS unit (Lowrance LMS350A) packed up (internal battery failed).
I was delighted to pick up a Lowrance Globalmap 2000 unit VERY cheaply (ebay, unit described as brand new, never used), and discussions with Lowrance confirmed that I should be able to plug the GM2000 into the exiting power cable left installed from the LMS350 and the GPS side should work (sonar a different matter, but have not got to that yet).
However, on powering up the GM2000, I get a "GPS reciever not responding" message. As I know the GPS antenna was working on the LMS350, this indicates to me that either the pin-outs on the two units are different, or there is a fault with the GM2000.
Lowrance insist the pin-outs for the GPS functions are identical, so what I would really like to do is check my GM2000 on some-one elses installation to try to establish if it really is the head unit which is faulty.
Anyone with a boat in striking distance of Hertfordshire with either a Globalmap 2000 (or 1000 I think) or a LMS-350A installation that I could plug my unit into to see if the "GPS reciever not responding" message is repeated?
Any other bright ideas?
