perryton, tx | You can get a null modem at Radio Shack or any similar store that sells electronics. I wish had a picture handy but mine are just about 6” long sections of serial cable that’s labeled null modem. I don’t think it matters where in the signal chain between the NAV and the 2630 you put it. I’m a little perplexed by your situation because your display says that you’re getting a signal…otherwise the little globe icon will just blink and it will say NONE. | |
