I got my 2006 GPGT in September, and absolutely love it. Replaced my 1998 GTP which was totaled when some moron took a left when they should have waited and hit my wife head on - totaling both vehicles. I bought my 2006 with 93k on it for $6,500.00 and have been really pleased. Loaded with everything expect on-star, as well as a magna-flow exhaust, K&N CAI, and AR casino wheels, it makes for a nice daily driver that still keeps the sport car demons partial satisfied in the winter months.
At any rate, the car has the OE remote start option, and the range on this this is just absymal. If I can get more that 20', I'm lucky. I can sometimes get near 30' of range if I do the "chin and point" method - boy does that look goofy. The manual calls for up to ~600' of range, what a joke. I've tried 2 new batteries, no improvement. I can't even start the thing from my upstairs rear bedroom when its in the garage directly behind my house.
Now, I've read some and this is apparently pretty common, but I'm hoping to start a new thread to get some idea's from you guys on what you're getting for range on the OE remote start Grand Prix's, and what you've done to improve the range. I see there is an aftermarket company that has a system to retrofit with the OE system to retain the automatic heating/air conditioning benefits of the OE system, but it seems like there must be a cheaper way to get better performance out of the this system.
