I have a whole slew of Garmin GPS units, my favorite one is the 2730 with the physical pushbuttons on the front. next best favorite was the 660 because it has an internal FM modulator... I ride Goldwing motorcycles, and being able to hear the GPS thru the radio's dash speakers was great! but, the 2730 won't stay powered up because the cable connector is loose from too many years of trucking down the highways. And, cables for GPS units are Very Finicky. More so that the average cellphone or other USB device. With that said, I am a brand new user, and looking for an answer to a specific question. What is the Torx Screwdriver size to remove the screws? T4 is too big, and that is the smallest one I have. I want to open up my 2797 and add an audio output cable across the speaker terminals. so wish that Garmin had not omitted that 3.5mm jack. Now, to the Main Topic: Garmin Support: The folks there are Script Readers, and their responses are guided by very narrow parameters. If you have Software Problems, they can usually walk you through a fix. If you have Hardware Problems, then you will receive the answer I got today: "Sorry, but all hardware designs questions are considered Propitiatory and Confidential" All I wanted to know, is the size of the Torx Screwdriver needed to open the case. The reply I got after the 'confidential message was' you will void the warranty if you open the GPS. No lie Sherlock, I had already gotten past that problem, it is a Refurb.... all I want is Audio out of the GPS. so, again, anyone know what size the screws are in the case for the 27xx series Nuvi GPS units?
