Navigation Installations; especially Eclipse

[kodiakz]

That sucks.....Thats What you get for getting an Eclipse navi. You should of got the Alpine!!!!!!!
NOT!!!! lol
We do more Eclipse navs than any other and never (knock knock knock wood) have any problems with them in any vehicles. I have never yet had a defective unit and I cannot say the same for Alp, Pio, or Kenwood. Not to say that the Eclipse is better than those in other ways, just seems to be better all around quality.
I would say that the shop installed it incorrectly and did not use the proper interface and/or switched 12v lead. When installed correctly, it will draw about the same as the Oem for clock/memory which is give or take 40ma--at that rate it would take about 1 month to run the battery down all other things being equal. If the Eclipse were causing battery drains, I would have many upset customers and I have none. Have your installer try another interface or try another brand of interface altogether as that could be the culprit.
