greetings,i just bought and installed a Lowrance hds-5 gps-sounder Combo, the Sounder works great.i am having some problems with the Gps, when i am running it works good, speed is close and follows along nicely on the Chart.when trolling the speed overground is eratic , sometimes as much as 900mph.This Unit has an internal Gps antenae.It is mounted in the Dash of a 20Ft.hardtop Hourston. Has anyone had an issue like this?Any feedback or suggestions would be much appreciated, thanks Drilleryells
