I purchased a GT350 in April and after driving it a few times found that first gear is good for 55 mph and the rest are good for getting me into a great deal of trouble! In come the ALP, after doing some research I found the system to be the top performer in the industry according to all who owned it. I purchased the 5 head laser jammer and integrated radar. I have been installing the system as a DIY project using the information available on the forum (which is very thorough). The only question I could not find an answer to is where to mount the GPS remote antenna, under the dash or on the windshield? Advise would be appreciated. AWSOME product, service, and support!
