I had purchased a Lowrance Elite 5 HDI combo unit back in January 2014 but unfortunately hadn't had much of a chance to use it, especially the maps and GPS functions since we rarely get to the salt water. However, last weekend we went to Hervey Bay in anticipation of having a red hot crack at some of the artificial reefs only to have the unit play up, freeze, lockup and lastly, no longer load any of the maps. I have just taken it back to the store where I bought it, they were fantastic and got on the phone with Navico who agreed to replace the unit even though the warranty had expired by about 6 months. I just wanted to share this good news story and say I can't recommend the Toowoomba supplier (a certain boating, fishing and camping store) and Navico for agreeing to replace the unit at no charge. I would suggest the fact that the unit still looks virtually new and has barely been used was probably a contributing factor, but still, I am pretty stoked!
