i am wondering what i should do.

any avice would be great.

i have the original z1 unit. i have all the accessories. such as the BT, tv, sirius, and xm modules.

there is nothing wrong with the unit. works perfectly fine.

the only issue i have is that the map is out dated. i am now at an impasse.

the price of updating it would be kinda costly just to updte an older unit. but the unit is working just fine otherwise.

i also dont know if all my current accessories such as the xm, sirius, BT unit will still work on the newer units.

i was thinking of the z130

what should i do?

is it worth paying for a new unit?

or is it worth just updating the map?
