Re: Radio stations not beiing memorised
There is suppose to be 2 power in for the radio 1 that holds memory for the radio has to be picked from a line that has power available to it even if the car is switched off and the other just to switch on the radio itself... check to verify that you have connected the memory power for the radio correctly and that that line has power even though the car is switched off...... use dc tester to test that it has power available

Your memory wire(12volt constant) and accessory (12volt switched) are in opposite positions. I have seen this happen with aftermarket wiring harnesses for european vehicles (mercedes,audi and VW). Switch the wires.
once you have the station you want to listen to on the radio press and hold one of the buttons along the bottom of the stereos face for a few seconds the screen should flash for a second or two or it should beep as well to indicate its saved it.
if when you turn the ignition off and then turn it back on the stereo has forgotten the station you programmed you need to remove the stereo from the car and check the wiring at the back of the unit. most of them have a red and yellow wire that are joined by metal push fit connectors, swap these two over and it will then remember the station for you.
the red wire is the switched power lead from the ignition and the yellow lead is a constant live feed for it to remember your settings, if these are round the wrong way it will keep forgetting radio stations you program until you switch them over.
There is an internal battery to hold the station and presets. It is probably no good. Either that or there is something very wrong with the unit.
Here is what I recommend. Call XM. Tell them your receiver is not longer functioning correctly and that you are thinking about canceling your service because you don't have a receiver. They will then offer you a receiver because they don't make much money on them, the make their money on the service.
Hi. On the back of the ISO lead switch the red and the yellow. The VW constant positive (station memory) comes off a different pin to other cars. Therefore when you are switching your engine off you are switching the memory power.
The radio was installed incorrectlly. Make sure the red wire from the radio is connected to a switched 12 volt source(has voltage when car is on, none when it's off) The yellow wire to a constant 12 volt(hot at all times) this wire mantains the radio memory and must always have power.
On the face of the stereo is a * button. Push this button then use the numbers on the face of the stereo to go directly to that station. Example, my favorite classical station is 90.7. Push the * then 907. This station will appear in display. Then push and hold for about 5 seconds the preset button you would like this station to be. The stereo will momentarily blink to a different station then come back. Station set.
