The standard 9-10FT cable lengths for the XM and NAV are not long enough for a "custom" install I'm thinking about attempting. It'd sure simplify things if I could just order pre-made cable to the length I need, but I'm not opposed to making them myself.

I just don't know what type cable/wire I need , or where to get it!!

Anyone know where to locate the kind of stuff I'm going to need?

A couple other questions:

Will lengthening the cable degrade the signal?

Better to have a one piece cable, without a "connector/splice"??

Thanks in advance......

The GPS antenna is 5 meters. Not sure if an extension would hurt your reception

For XM, I remember there were 20 and 50 foot extenstions at best buy a few years ago, so I am sure they are still out there somewhere. Might work on the GPS too, but who knows?

Thank you........... Now the search begins!
