Same problem here, when plugged in, no GPS reception and keyless features only work about 3 feet away. Unplugged, everything works fine.

Thanks Guys, You would think they would make a 90 degree adapter? Oh well, Still looking...

Thanks for the link, dont really have any soldering skills, drink way too much coffee, mine would look like one big ball shiny solder connecting every wire end

Thanks All!

Hi,
Can anyone tell me if the Trinity supports shift point changes in a 2008 Hummer H2. If not, when would it be available or will be available?

Thanks!
