I have done a search and read many posts on the problems related to the 8500 and false laser alerts. I still have a question or two for the pro's on this site.
I have been getting a constant false laser alarm at various locations over the past few months. I have a 2000 Jeep Grand Cherakee. The 8500 is about 2 to 3 years old and is powered with the cig lighter cord and has been since I got it The only thing I have done electricaly over the past few months is switch from XM radio to Sirius. I don't think that is the problem because the false laser happens when the Sat radio is on and off.
When I go to one local super market I almost always get a Self Calc when I turn my car back on. It goes throught the self calc for about 30 sec and then its back to normal. I don't know if this has caused any problems or not. I have Never gotten a "service required" message. .
What should I do? Send it back and get it repaired? I think they wanted $80 and mentioned something about checking filters. That price seems very high. Almost a third of the purchase price. I read a post where someone discribed how he soldered some of the wires inside the unit. I could do that but it sounds very dicy. If you mess up there is no way they would fix it then. Another post recommend adding capacitors but I don't know how to do that. I also don't know what Rev the unit is. Would that make a difference? I could check but how could you update it?
Thanks for any help.
