Where to mount gps antenna?

I bought a gps reciver off ebay and it came with no instructions. I found all the wiring diagrams I needed online but my google fu is no good and I cannot figure out where I am supposed to mount the antenna for the gps. It has bout 6-7' of cable and a magnetic mount. Under the hood ? On the Dash ? Behind the dash? Model -ECLIPSE AVN2210P

 

I ran my antenna to the right of the head unit behind the glove box and pushed the wire in snug until I only had the little box showing rim the farthest right hand corner of the dash. I didn even tape it down, it isn't going anywhere and the signal is great on my AVN726

 

hendooman's idea looks pretty good. The directions for my AVN726e said to place it 20 or so inches from the head unit. I ran the connector end through the top of the defroster vent holes in the center area of the dash and used my other hand to reach behind the head unit area and catch the wire. I had to fold back the edge of the defroster compartment as it met the underside of the dash. It might be a little hard if you have large hands. Anyway, my antenna isnt the required 20 inches away from the unit but i still have perfect satellite signal. I would have liked to route it behind the driver side dash, that way it would have been completely hidden from view, but it would have been harder...for me at least.

 

Mine is under the dash.

 

I have a Kenwood DNX6960 and ran my antenna cable under the dash to the left. I took off the plastic cover on the left window frame upright and just put the wire through there with plenty of space. Put the cover back on the upright and then just let the antenna rest in the corner. Maybe a little double sided tape to keep the car wash nazis from tearing it up but that's about it and I get great signal all the time.

 

I just put mine in last week right above the head unit bit under the dash. Just use some Velcro. My signal is always strong.

I've had my GPS antenna above the radio under the plastic dash for 2 years now and it works perfectly. I've never had any issue "seeing" any satellites.

 

I ran the wire through the firewall into the engine compartment and then route it to the top of the front hood. It is hidden nicely behind the hood protector.
